Data Sheet:
The preface section of all BOTC-TEGs is a data sheet that provides quick view information for weight, relay rack
footprint, peak (LIST 2)/nominal (LIST 1) power amperage, heat dissipation wattage, timing, alarms/remote
management, DF block and CLEI code requirements. The data shown is an ultimate condition (relay rack fully
loaded with equipment as designed in associated BOTC-TEG). Even though many relay rack deployments are
partially equipped, BOTC recommends basing initial space/engineering planning on ultimate data since existing
rack layouts typically grow to conclusion without follow-up involvement by planning personnel.

BOTC-TEG-1160
1. Overview:
Service Providers/Telcos are deploying Internet Protocol (IP) distribution networks for voice, data and video
services. A small number of Super Hub Office (SHO) locations have been established to provide collection points
for national video programming. SHO fiber circuits link up to the nearest Service Provider/Telco Point Of Presence
(POP) for nationwide, backbone transport. National voice/data/video signals are then routed to POPs in major
demographic areas and handed off to a Video Hub Office (VHO). Local video programming is collected at the VHO
and blended into the national voice/data/video signal. Routers and switches (Alcatel 7750 SR-12 and 7450 ESS-7
for example) are then used to distribute this combined service to Central Offices (CO) in the demographic area.
Alcatel 7342 Packet Optical Line Termination (P-OLT) equipment transports IP voice/data/video (triple play)
services to customers using Passive Optic Network (PON) fiber. This version of IP triple play is called Fiber To The
Prem (FTTP) or Fiber To The User (FTTU). The 7342 shelf has 21 slots (1 alarm card, 2 redundant network cards,
18 PON cards). The network cards have 1 Gigabit Ethernet (1Gig-E) fiber circuits to a CO IP switch (7450 ESS-7)
via FDF cross connects. The number of 1Gig-E circuits (see section 7 part G consultation step) depends on the
expected sum bandwidth requirement for all customers served by the shelf, customer usage ratios and multicast
(on demand) versus unicast video offerings. Each PON card has two bidirectional single conductor fibers that cross
connect with outside plant fiber at the CO FDF. The outside plant fiber runs to optic splitter units (16 to 1 or 32 to
1 depending on signal strength, see section 6) located in customer neighborhoods. Based on this split ratio, a 7342
shelf can serve 576 to 1152 customers. An Alcatel Home Optical Network Terminal (H-ONT) and back-up battery
device are placed at the customer site for conversion of PON fiber into electrical voice/data/video signals.
If all FTTP/FTTU customers served by a given CO want full IP service (including Voice over Internet Protocol or
VoIP), a voice gateway interface to the Class 5 CO switch is not required. Since it’s probable that some customers
will want to keep their traditional voice service (instead of VoIP), most FTTP/FTTU COs will need to establish the
voice gateway using General Bandwidth G6 equipment. The G6 shelf has up to 110 DS1 circuits (11 cables with
mixed TX/RX, see BOTC-SEG-0100 section 6 part C) connecting to DSX-1 (if the CO switch interface is Lucent 5ESS
IDCU, Nortel ESMA, Siemens LTGK for example) or DACS/Titan DCS (if DS1 to STS-1 conversion is required due to
Lucent 5ESS DNUS interface). 1Gig-E fiber circuits are run from the G6 shelf to CO IP Switch (7450 ESS-7) ports.
The 7450 functions as a voice aggregator (blends traditional voice service with IP data/video as required) and
includes this feature on the 7342 network card 1Gig-E circuits.
2. Version L shelf with quad port PON cards not recommended at this time:
This TEG supports the 7342 version K shelf (see section 3 part number) with dual port PON cards. Current Alcatel
documentation (Feature Group 4.4.0) for 7342 includes an optional 3FE51055AA version L shelf with quad port
PON cards (doubles system capacity). The following items provide a comparison of these two configurations:
Card layout: Both shelves have 21 slots but with different layouts (reading left to right, K is 1 alarm, 2 network, 18
PON and L is 9 PON, 1 network, 1 alarm, 1 network, 9 PON).
Fiber management: Both shelves manage network card fiber using a lower left front channel. K shelves manage
PON fiber via clips along the top front shelf edge (PON card fiber connectors angle up) and then into an integrated
shelf baffle. L shelves manage PON fiber via a bottom front shelf channel (PON card fiber connectors angle down).
Fan design: K shelves (22.75” high) have an internal fan assembly. L shelves (21” high) require a separate rack
mount 3FE51299AA AFAN-R shelf (3” high) mounted below.
Redundant path between network cards: K shelves require a front side 10Gig-E electrical jumper between the
two redundant network cards (see section 7 part G). L shelves provide the same electrical path internally (within
backplane).

BOTC-TEG-1160
Power requirements: Alcatel’s latest 7342 documentation (4.4.0, June 2007) is not complete regarding GLT4-A
quad port PON card power requirements. 3FE51201 (Planning & Ordering manual) section 3.9 table 3-7 shows
typical and maximum wattage for all card types except the quad port PON (listed with “ – “ in wattage columns).
3FE51205 (Hardware Installation manual) DLP 141 indicates 40 amp external fusing for L shelves. K shelf LIST 2,
LIST1 and heat dissipation power requirements are clearly documented (see Data Sheet in this TEG).
At this time, BOTC does not recommend the 7342 version L shelf/quad port PON card configuration due to
uncertainty about the power requirements. CO BDFBs are normally designed for a maximum 60 or 70 amp output
fuse size which limits NE racks to 48 or 56 amps LIST 2 (see BOTC-SEG-0500 section 11 overprotection rule). The
K shelf/dual port PON card configuration LIST 2 is 47.9 amps per two shelf rack. Based on Alcatel’s DLP 141 (40
amp fuse at rack fuse panel), each L shelf could have a LIST 2 in the 30 amp range. This would limit 7342 racks to
one L shelf unless BDFB outputs were modified for larger fuses (very expensive). L shelf heat dissipation wattage
is probably so high that anything more than one shelf per rack may create an equipment damaging heat island (see
BOTC-SEG-0600 section 8). One shelf per rack also raises issues with floor space efficiency and deployment costs.

FIGURE 4A
Layout for Alcatel 7342 P-OLT rack (version K shelves with dual port PON cards).
Rack is limited to two 7342 shelves (instead of three) since CO BDFBs are normally designed for a maximum 60 or
70 amp output fuse size which restricts NE racks to 48 or 56 amps LIST 2 (see BOTC-SEG-0500 section 11
overprotection rule). The 7342 K shelf/dual port PON card configuration LIST 2 is 47.9 amps for a two shelf rack.
Provide 2" x 2" vertical fiber protection duct on left front upright down to shelf 1 level.

BOTC-TEG-1160
5. Relationship of heat dissipation methods and rack footprint:
BOTC-SEG-0600 section 8 provides an overview of various heat dissipation methods. 7342 P-OLT shelf (version K
with dual port PON cards) heat dissipation is 800 watts (1600 watts for a two shelf rack). Prior to engineering new
7342 P-OLT equipment racks, vendors must consult with Service Provider/Telco personnel. If method 8C is used
(Space Planner fully manages and balances heat issue on each NE rack deployment job), increasing the rack
footprint width to compensate for heat (by using left/right spacers) is not required. If method 8A (100 watts per
square foot) or 8B (arbitrary limit) is used, left/right spacers are required to increase rack footprint so it meets the
given watts per square foot standard. BOTC does not recommend artificially increasing the rack depth (creates CO
placement issues for Space Planners) or reducing the number of 7342 shelves per rack (inefficient use of BDFB
assignments and rack fuse panel) to meet the wattage standard.
6. Minimizing PON optical loss:
As shown in section 1, each outside plant PON circuit is split 16 or 32 times depending on signal strength at the
customer neighborhood location. To prevent unnecessary use of 1 x 16 splitters (reduces PON efficiency by 50
percent), optical loss must be minimized between the 7342 shelf and FDF cross connect to outside plant fiber.
Each full FDF panel connection (two fiber connectors terminating on panel bulkhead) has an average loss of about
0.3dB. This equates to about 3000 feet of fiber. Some COs have a main FDF (interface with outside plant) on one
floor with satellite FDFs on other floors. In many cases, transport equipment fiber circuits will run through several
FDF panels before reaching the final outside plant interface. When engineering 7342 P-OLT equipment, every
attempt should be made to reduce the potential number of FDF cross connect points. This may include placement
of 7342 racks on the main FDF floor (when the CO design would normally place transport equipment on another
floor) or using direct fiber cable runs from 7342 GLT2-B cards on one floor to the main FDF on another floor.
7. System connection details:
A) Fuse panel:
Step (Dual load input feeders from BDFB): See BOTC-SEG-0500 section 11 for BDFB fuse/feeder sizing
responsibility and BOTC-SEG-0700 section 9 for wire material. Provide 4 two hole lugs (.25” studs on .75” centers)
for input feeder connections (wire size determined by vendor based on job conditions). LIST 2 (at 42.6V) for a two
shelf 7342 rack is 47.9 amps on the A load (20.9 for each 7342 shelf redundant with load B and 3.05 for each single
load internal fan unit) and 41.8 amps on the B load (redundant with A load). See BOTC-SEG-0500 section 2.
Step 2 (Chassis ground): Provide 1 two hole lug (.25” studs on .625” centers) for 6 AWG wire. Bolts and washers
are included with the fuse panel. Since excessive tightening of these bolts may strip threads in the chassis side
panel, torque each bolt to 4 foot-pounds (do not overtighten). Connect lug to relay rack ground using 6 AWG wire
(see BOTC-SEG-0700 section 7 and 9).
Step 3 (Alarms): Run 24 AWG Yellow/Yellow-Green, Red/Red-Green wire quad (see BOTC-SEG-0700 section 8)
from fuse panel Fuse Alarm and Power Alarm NO/C wire wrap pins to CO alarm system (Dantel for example) status
points.
B) Power for 7342 shelf:
Step 1 (intra-rack wiring): Connect TB1 lug 1 (RTN A), lug 2 (BATT A), lug 3 (RTN B) and lug 4 (BATT B) to rack
fuse panel TPA output positions using 10 AWG Slate wire (see BOTC-SEG-0700 section 7 and 9). Provide Thomas &
Betts (or generic equivalent) RC484 ring terminals for 7342 shelf end and RC10-10 for fuse panel end.
Step 2 (fuse panel fuses): Fuse externally at 30 amp. See BOTC-SEG-0500 section 14 for TPA fuse part number.
6
BOTC-TEG-1160
C) Power for 7342 shelf internal fan unit:
Step 1 (intra-rack wiring): Connect TB1 lug 5 (FAN BATT) to rack fuse panel GMT output position using single
22 AWG Red-Black wire from Black/Red-Black pair (see BOTC-SEG-0700 section 8). Provide Thomas & Betts (or
generic equivalent) RA484 ring terminals for 7342 shelf and fuse panel ends.
Step 2 (fuse panel fuses and designation pins): Fuse externally at 4 amp. See BOTC-SEG-0500 section 14 for
GMT fuse and designation pin part numbers.
D) Chassis and Earth ground for 7342 shelf:
Step 1 (intra-rack wiring): Connect TB1 lug 7 (EARTH GND) and lug 8 (FRAME GND) to relay rack ground using
spare 10 AWG Slate wire from part B. Provide Thomas & Betts (or generic equivalent) RC484 ring terminals for
7342 shelf end.
E) Timing for 7342 shelf:
Step 1 (mount BITS-A board): 3FE50327AA BITS-A board (see section 3 part E) includes 3EM18155AAAARJZZA
instruction sheet. Board mounts on rear side of 7342 shelf just above the BITS INTFC pinfield. Board comes with
pigtail wiring that should be connected as follows:
Board PRI-T pin White lead to 7342 shelf BITS INTFC PRI-T pin.
Board PRI-R pin Blue lead to 7342 shelf BITS INTFC PRI-R pin.
Board SEC-T pin White lead to 7342 shelf BITS INTFC SEC-T pin.
Board SEC-R pin Blue lead to 7342 shelf BITS INTFC SEC-R pin.
Connection of the pigtail shield drain wires is not required at Board or BITS INTFC ends since this is very short
intra-rack wiring.
Step 2 ( external timing cables): See BOTC-SEG-0100 section 9 for methods. Run two single pair timing cables
from shelf BITS-A board to CO BITS distribution equipment DS1 outputs. Connect primary pair to shelf BITS-A
board pins PRI-T (Tip lead), PRI-R (Ring lead) and secondary pair to pins SEC-T, SEC-R. Do not ground cables at
shelf end (no capacitive ground feature).
F) RS232 back-up remote management for 7342 shelf:
7342 shelf electronics are manufacturer designed for in-band remote management via fiber overhead to an
upstream IP switch (Alcatel 7450 ESS-7 for example). This RS232 connection is an optional back-up link that
should only be run when directed to do so by Service Provider/Telco personnel. The 7342 shelf has wire wrap
RS232 pins on upper right rear of backplane).
Step 1 (attach stub cable): 3EC36078AA RS232 craft stub cable (see section 3 part F) wires to 7342 shelf pins as
follows: Stub White/Blue lead to DCD pin, White/Orange lead to RXD, Blue/White to TXD, Green/White to DTR,
White/Green to EG, Orange/White to DSR, Brown/White to RTS, White/Brown to CTS, White/Slate to RI. The stub
DB9 female connector is DCE rated with pin 1 DCD/OUT, 2 RXD/OUT, 3 TXD/IN, 4 DTR/IN, 5 GND, 6 DSR/OUT, 7
RTS/IN, 8 CTS/OUT, 9 RI/IN.
Step 2 (external remote management cable): Provide one of the cables shown below and run from DB9 female
end of stub cable to CO Remote management system. See BOTC-SEG-0100 section 11. XXX in cable part number
denotes footage. If far end is:
Applied Innovation AI-Scout or AI-180/AI-130 switch with DP232-23 DB25 asynch patch panel, provide Black Box
(www.blackbox.com) CBCC204261-XXX DB9 male to DB25 male cable.
Applied Innovation AI-180/AI-130 switch with DP232-RJ45 panel, provide Westek (www.westekelectronics.com)
DT280116/XXX DB9 male to RJ45 male cable.
Cisco 2511 router, provide Westek DT280119/XXX DB9 male to RJ45 male cable.
Cisco 3662 router, provide Great Lakes (www.greatwire.com) 96882-XXX DB9 male to HD60 male cable.
7
BOTC-TEG-1160
G) Network fiber for 7342 shelf:
Step 1 (consult with Service Provider/Telco): Engineering vendors should consult with Service Provider/Telco
personnel about the required number of CO IP switch (7450 ESS-7 for example) 1Gig-E circuits. This depends on
the expected sum bandwidth requirement for all customers served by the shelf, customer usage ratios and
multicast (on demand) versus unicast video offerings.
Step 2 (connect 10Gig-E electrical jumper): 3EM19465AA electrical 10Gig-E jumper kit (section 3 part P) is
required between slot A and slot B EHNT-A cards. Mount XFP modules (provided with jumper kit) in 10GbE-2 XO
position on both cards. Connect jumper from XFP on slot A card to XFP on slot B card.
Step 3 (run fiber conductors): Each EHNT-A card has four positions (1GbE-1, 1GbE-2, 1GbE-3, 1GbE-4) for SFP
modules (see section 3 part N). SFP has one set of TX/RX ports with LC connectors. Run 2 fiber conductors (see
BOTC-SEG-0400) from each equipped SFP to the FDF. Cross connect is to CO IP switch (7450 ESS-7 for example)
1Gig-E port. Route fiber from EHNT-A cards through channel in lower left of shelf. Per section 4 figure 4A, vertical
duct material should be provided on the 7342 rack left front upright for protection and management of fiber
conductors.
H) PON fiber for 7342 shelf:
Step 1 (run fiber conductors): Shelf has 18 slots for GLT2-B cards (section 3 part K). Each GLT2-B has two
bidirectional SC connectors designated PON 1 and PON 2. Run 2 fiber conductors (see BOTC-SEG-0400) from each
GLT2-B card (total of 36 conductors for shelf) to the FDF. If fiber jumpers are used (instead of fiber cable) they
must be single conductor (dual conductor jumpers will not dress properly on the GLT2-B card face). Route fiber
from GLT2-B cards through clips along top edge of shelf and then into top baffle (part of shelf chassis). Cross
connect is to outside plant fiber.
