Z-Edge 64 Configuration Guide
The following table defines the CID ranges for voice connections based on
loop emulation using AAL2 (specified in AF-VMOA-0145.000). Use these
ranges when assigning CIDs in the aal2-cid-profile:
Modify the following parameters in the aal2-vcl-profile to match your
network:

Description
16...127
POTS
128..159
D-channels for ISDN BRI
160..223
B-channels for ISDN BRI
Parameter
Description
app-id
Application Identifier. It specifies the protocol used between the IAD and
the ATM switch.
Values:
caspotsonlynoelcp Loop Emulation Service using Channel Associated
Signaling (CAS) without Emulated Loop Control Protocol (ELCP), which is
used for POTS.
dss1brionlynoelcp Loop Emulation Service using Digital Subscriber
Signaling System number 1 (DSS1) in support of ISDN BRI without ELCP.
audio-profile-identifier
From the aal2-audio-profile, the audio-profile-identifier is an index
number that refers to the type of audio service provided.
Values:
7 for G..711 or G.726, 44-octet packets, and silence-suppression
8 for G.711, 44-octet packets, and silence-suppression
sscs-default-type
The Service Specific Convergence Sublayer (SSCS) is the portion of the
convergence sublayer that is dependent on the type of traffic that is being
converted. Channels that are used to carry media streams (POTS or ISDN B
channels) use the SSCS defined in I.366.2. Channels that are used to carry
control and management plane traffic (CCS, ELCP, ISDN D channels, and
LES-EOC) use the SSCS defined in I.366.1.
Values:
i3661 for ISDN D channels
i3662 for POTS and ISDN B channels
Default: i3662
max-cid-for-aal2-user-channels
Maximum Channel Identifier (max-cid) value for AAL2 user channels as
defined by the ATM Forum. Refer to
for CID values.
