Note: To use features on Enterprise Edge remotely, press * followed by the

code. Even if you are calling from another Enterprise Edge

system, press * instead of Feature.

For more information on remote system access on various trunk types, refer to:

• Remote access on loop start trunks on page 331

• Remote access on a private network on page 331

• Remote access on T1 Direct Inward Dial (DID) trunks on page 332

• Remote access on PRI trunks on page 332

• Remote access on DPNSS lines on page 332

Remote access on loop start trunks

Loop start trunks provide remote access to Enterprise Edge 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 operatein

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, the system

answers with system dial tone and no (COS) password is required. In this case,

control over the system capabilities available to the caller is provided only by the

restriction filters assigned to the line.

When a callerdials 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 which

determines which system capabilities are available to the caller.

Remote access on a private network

Nodes on the private network deliver the last dialed digits to the destination

Enterprise Edge node for interpretation. The destination Enterprise Edge node

either matches the digits to a target line or interprets the digits as a remote feature

request. The call is either routed to the specified target line, or the remote feature is

activated.

By default, T1 E&M trunks are set to answer with DISA. For auto-answer T1 E&M

trunks connected to a private network, change the default so that the trunks are not

answered with DISA.

If an auto-answer T1 E&M trunk is configured to answer with DISA, the system

tries to interpret any received digits as a COS password.

The DISA DN and the Auto DN allow auto-answer private network and DID calls,

in the same way that calls on auto-answer loop start and auto-answer T1 E&M

trunks can be answered, with or without DISA. These DNs are described in Access

codes on page 156 of the Configuring Enterprise Edge Services chapter.
