A single T1/E1 CESM card can provide standby redundancy for all active CESM cards of the same
type in the shelf (N:1 redundancy), with SRM.
CESM cards are supported by standards-based management tools, including Simple Network
Management Protocol (SNMP), Trivial File Transfer Protocol (TFTP) for configuration and
statistics collection, and a command-line interface. Cisco WAN Manager also provides full
graphical user interface (GUI) support for connection and equipment management.
1:N redundancy requires that the group contain one redundancy back card.
The redundancy back card must be the special R-RJ45 version (AX-R-RJ48-8T1-LM or
AX-R-SMB-8E1-LM).
