Cmas - Alcatel-Lucent 7750 SR OS Interface Configuration Manual

Configuration Overview

CMAs

CMAs (Compact Media Adapter) are configured and provisioned in the same manner as MDAs
(Media Dependent Adapter). 7750 SR-c12 and SR-c4 systems accept CMAs. Up to eight CMAs
may be provisioned on a 7750 SR-c12, and up to 4 CMAs may be provisioned on an SR-c4. .
CMA output displays a "c" in the name of the card. The following displays a
command. In this example, a c8-10/100eth-tx CMA is installed in slot 5.

A preprovisioned CMA slot can remain empty without conflicting with populated slots.
Once installed and enabled, the system verifies that the installed CMA type matches the
configured parameters. If the parameters do not match, the CMA remains offline.
Note: On the E3 CMA, bit stuffing is not supported in G.751 framing mode. All of the 12
justification service bits and the 4 justification bits contain valid data on the transmitted signal.
Incoming bitstreams should contain valid data in the 12 justification service bits and 4 justification
bits, otherwise the link will not function.
