When equipping OC48 high speed slots, it is imperative that the switch
fabric of the circuit packs located in Main 1 and Main 2 match. For
example an LNW 26B located in Main 1 may be used with any
LNW121B-159B DWDM circuit pack in Main 2, since both have par-
tial (up to 12 STS-1s) VT mapping. If circuit packs with different fab-
rics are inserted in Main 1 and Main 2, for instance, an LNW29 were to
be inserted in Main 2 with an LNW26B present in Main 1, an "unex-
pected circuit pack type" alarm would be raised.
The following is a list of Main OLIU circuit packs, grouped by compat-
ible switch fabric.
• Circuit Packs with 6 STS-1 switch fabric:
LNW26
LNW26B (jumper set to normal mode)
LNW28 (jumper set to normal mode)
LNW77 (jumper set to normal mode)
LNW121B - 159B (jumper set to normal mode)
