Table 2 -30 describes the LEDs on the SRM-3T3/C and SRME/B.
SRME
Supported models: MGX 8850 (PXM1E/PXM45), MGX 8850/B (PXM1E/PXM45), MGX 8830, MGX 8830/B
The SRME provides bulk distribution for T1 and E1 lines, 1:N card set redundancy for T1 and E1 s ervice
modules, and BERT. Bulk distribution is managed over 155 Mbps interfaces through use of OC-3c or
STM1. The SRME also supports APS line redundancy when the OC- 3c back card is used.
