Chapter 53 Call Security: Configuring Direct Inward System Access (DISA) 459

BCM 4.0 Networking Configuration Guide

Setting up remote access on lines

Setting up remote access on different types of trunks requires you to understand the trunk

properties and how you want the system to answer the dial-in calls.

Refer to the following topics:

• “Remote access on loop start trunks” on page 459

• “Remote access on T1 DID trunks” on page 459

• “Remote access on PRI” on page 460

• “Remote access on DPNSS lines” on page 460

• “Remote access on a private network” on page 461

• “Other programming” on page 461

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. Refer to “Configuring lines:

T1-Loop start” on page 193.

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 restriction filters

assigned to the line control system capabilities available to the caller.

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 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.

• The digits received are delivered by the central office.

• DISA cannot be administered to a T1 DID 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.

Refer to “Configuring lines: T1-E&M” on page 187, “Configuring lines: T1-DID” on page 205.
