AAL2 CID profiles
Create an aal2-cid-profile for each voice line. The traffic will go over the
same interface (WAN: 1/1/1/0), but each virtual voice connection will be
differentiated by an AAL2 Channel Identifier (CID).
Modify the following parameters in the aal2-cid-profile to configure CID
settings:
POTS
For POTS, create one aal2-cid-profile for each voice port. The syntax is new
aal2-cid-profile shelf/slot/port/subport/type/vpi/vci/cid. This example is
voice port 1, and it uses the lowest ATM Forum-specified CID for POTS:
zSH> new aal2-cid-profile 1-1-1-0-hdsl2/atm/0/37/16
