Note: 9X40DA ENET Paddle Board connects to front of CEMs.
Note: SPM Module with two shelves can provide up to 26 Resource Mod-
ules (RM) in addition to the required CEM and SIM circuit packs.
Note: Each serial link (SL) has 256 time slots. Where 3 SLs are assigned,
there are 768 timeslots that can service the bandwidth equivalent to
one STS-1 or DS-3 Resource Module.
Note: Serial links in dia-
gram above are shown as 1-S, 3-S, and 9-S.
Note: Slots 1 & 2 and 9 & 10 of shelf 0 have 9 S-links or 2304 timeslots
that supports OC-3 or ATM RMs to provide 2016 circuits.
Note:
Prior to SP14, if you plan on implementing ISUP trunking, you
must have LIU7s datafilled and configured for external routing (See
NTP 297-8991-030, LIU7 Ext. Routing Activation User Guide)
Note: For further description of the following SPM shelf packs, see “Cir-
cuit Pack Description” within this QRG or see NTP 297-1771-550.
LX57 — PCIU Card LX56 — Fan Unit Card
LX58 — Alarm Card LX59 — Fan Management Unit LX60 — Filler
LX5015 - Air Filter (#0665487) LX5016 - Air Filter Tray
LX61 — Shelf Interface Module (SIM) (Power Distribution & Alarms) is
located in slot 15 of each shelf.
LX82 — Enhanced Common Equipment Module (CEM) with Ethernet is
located in slots 7 and 8 of the bottom shelf. The LX82 CEMs are required
for Crossover Messaging functionality and Succession Evolution of SPMs.
See “Verifying Crossover Messaging” on the next page.
Note:
Use PRSM
command ISTBAUDIT to confirm CEM patches. ex:
>ISTBAUDIT <spm #><cem #>
Resource Modules and Provisioning Information
Important Note: Only one type of ECAN RM can co-exist in the same
SPM. You cannot mix LX66 with LX85 or LX86 RMs. You also cannot
mix LX85 and LX86 RMs within the same SPM.
LX44 — Sync Resource Module for Building Int. Timing Source (BITS)
LX65 — Digital Signal Processor (DSP) (Resources - MF, COT, ABBIT,
TONESYN) A DSP has 9 Islands. Note: You can mix LX65AA and
LX65BA DSPs in the same SPM.
LX66 — Voice Signal Processor (VSP) (Echo Cancelling (ECAN)). A
VSP has 10 Islands & 26 ECANs per Island, for 260 ECANs per VSP max.
Note: LX65 DSP and LX66 VSP packs go in slots 3 thru 6 & 11 thru 14 of
the bottom shelf and/or slots 3 thru 6 and 9 thru 14 of the top shelf (Need 3
S-links per shelf)
LX71 — OC-3 Interface Module (OC-3 Xmit & Rec. for Act/Prot) for
TDM (traditional trunking) packs go in slots 9 & 10 of bottom shelf.
LX72 — Data Link Controller (DLC) packs for supporting ISDN PRI ‘D’
Channel should go in slots 1, 2, 7 and 8 of the top shelf since they only
need 1 S-link per slot. Note: DLCs can go in other than slots with 1 S-link
but it would be wasting S-links.
LX73 — Asynchronous Transfer Mode (ATM) Interface Module packs go
in bottom shelf slots 1 & 2 for the “MG4K” (MG4000) SPM configuration,
and 9 & 10 of the bottom shelf for the IW SPM (The ATM pack needs 9
S-links per slot)
LX74 — Synchronous Transport Signal-level one (STS-1) Interface Mod
LX84AA — PCM30 Low Speed Access (LSA) LX84DA — DS1 LSA
LX85 — Voice Signal Processor (VSP) (i.e. echo cancellation)(MD)
LX86 — Voice Signal Processor (VSP) (i.e. echo cancellation)
LX99 — Synchronous Transfer Mode 1 (STM-1) Interface Module
Determining SPM Trunk Terminal & Node Numbers
Note: Unless you know the SPM and the and circuit numbers, locate it in
table TRKMEM.
TRKMEM Ex: SRMPODNWDS0 255 0 SPM 1 98 5
Note: In this example for trunk 255 in the SRMPODNWDS0 trunk group,
98 is the ckt # (span #) and 5 is the circuit (channel #) in SPM 1.
Note: Terminal Number (TN) = (Span X 24) + Channel (Channel = 1-24)
Note: SPM ckt #’s start at 95 which is span 0; therefore, circuit 98 in this
example would be span 3. Since we now know the span is 3 and the
channel is 5, we can figure the terminal number. Terminal Number
is: (3 X 24 + 5) = 77
Note: To get node number (NODENO), you can use XPMIST. Ex:
>XPMIST;NODENO SPM 1
Note: Another way to get an SPM trunk TN and NODENO is to go into
toss-up and turn PMIST on. Once in PMIST, use the command
>CONVERT TRK SRMPODNWS0 255. The output will be in
HEX so convert to decimal if needed
