Remote access on loop start trunks
Loop start trunks provide remote access to BCM from the public network. They must be
configured to be auto-answer to provide remote system access.
A loop start trunk must have disconnect supervision if it is to operate in the auto-answer mode.
T1 E&M trunks always operate in disconnect supervised mode.
When a caller dials into the system on a line that has auto-answer without DISA, the system
answers with system dial tone and no CoS password is required. In this case, the remote access
package assigned to the line controls system capabilities.
When a caller dials in on a line that has auto-answer with DISA, the system answers with stuttered
dial tone. This is the prompt to enter a CoS password that determines which system capabilities are
available to the caller.
Remote access on T1 DID and PRI trunks
Remote system access on T1 DID trunks is similar to that of T1 E&M trunks connected to a
private network. The main differences are:
• A remote caller is on the public network dialing standard local or long distance telephone
numbers.
• DISA cannot be administered to a T1 DID and PRI trunk. You can program the dialed digits to
match those of a specific target line DN, the DISA DN or the Auto DN. If you program the
dialed digits to the DISA DN, only the incoming calls that match the programmed DN will
receive a DISA dial tone. Incoming calls with other digits will route to a target line.
Remote access on DPNSS lines
A remote caller can access a BCM system dial tone, select a line pool that contains exchange lines
or DPNSS lines, then dial a number. The procedure is identical to dialing an outside number from
an extension in the local system. The main features are:
