	TEIs, and B-Channel provisioning

Example:

This command string configures the port for 128K Clear Channel, enters a leased-line dial string, saves the configuration, and restarts the network:

AT%A2=0@B0=2&M2&Z=”B1”&L1&W>W>Z [enter]

Note: enter AT&L1 as one of the last commands to prevent the unit from attempting to connect immediately. Entering commands as shown in the example prevents the unit from connecting unexpectedly, before it has accepted the entire command and saved the configuration.
