Card and Service Configuration 6-47
Service Resource Module
Service Resource Module
This section describes how to use the features of the T3 version of the Service Resource Module
(MGX-SRM-3T3/B). This multipurpose card can provide:
• De-mulitplexing of T3 service called bulk distribution.
• 1:N redundancy support for service modules with T1 or E1 lines.
• Bit error rate testing (BERT) for T3, E3, T1, E1, fractional T1, or subrate operation with loopback
pattern generation and verification on individual lines or logical port. For a description of the
BERT functions, see the section titled “Bit Error Rate Testing Through an MGX-SRM-3T3.”
An MGX-SRM-3T3/B installation requires at least one card set in the upper bay of the card cage and
one card set in the lower bay. Each set services one half of the backplane. The PXM in slot 7 controls
the SRMs in slots 15 and 31. The PXM in slot 8 controls the redundant SRMs in slots 16 and 32. If
the switch has SRMs with redundant PXMs, the SRMs must occupy all the reserved slots for this
feature—15, 16, 31, and 32.
Configuring Card and Line Parameters
You can configure card and line-level parameters for an SRM through the CiscoView application or
the CLI on the PXM (not the SRM itself. For descriptions of the commands, see the Cisco MGX 8850
Wide Area Edge Switch Command Reference. The CLI commands that apply to the SRM are:
• addln
• delln
• cnfln
• dspln
• dsplns
• addlmiloop
