Configuring E1 lines
Each built-in E1 line contains 32 channels, each of which can support one single-channel
connection. Depending on the signalling mode used on the line, all 32 channels are available
for user data, or 31 channels are available for data with the 32nd is reserved for signalling. E1
line configuration parameters are in a Line Config profile, as shown in the following example
for a MAX 4000/6000:

Note: The Ch N parameters are repeated for each channel in the line (31 channels if PRI
signalling is used, and 32 channels if robbed-bit.)
At the top level, you can assign a name to the line configuration. You can configure several
profiles and activate a profile when it is needed.
You can set line 1 and line 2 to Trunk (indicating a standard E1 interface with signalling
information) or Disabled.
The ETSI series of standards does not include a specification for how a CPE unit disables a
NET5 line. Therefore, if you disable an E1 line, the switch to which your MultiVoice Gateway
is connected does not take the line out of service when you save the profile. The MultiVoice
Gateway disables outgoing call requests for a disabled line, but the switch still delivers
