Remote access on T1 Direct Inward Dial (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

As with a private network, the dialed digits may be programmed to match those of

a specific target line DN, the DISA DN or the Auto DN.

Remote access on PRI trunks

Remote system access on PRI 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

• answer with DISA cannot be administered to a PRI trunk

As with a private network, the dialed digits may be programmed to match those of

a specific target line DN, the DISA DN or the Auto DN.

Remote access on DPNSS lines

A remote caller can access a Enterprise Edge system dial tone, select a line pool that

contains exchange lines or DPNSS lines, then dial a number. The procedure is

identical to dialling an outside number from an extension in the local system. The

main features are:

• Calls coming from another switch to the Enterprise Edge system can be routed

intwo ways, dependingon the Answer mode that you program. If Answermode

is set to Manual and the line is assigned to ring at an extension, the incoming

call automatically rings at the assigned extension. If Answer mode is set to

Auto, the incoming call is answered automatically by the CCU. Because most

other DPNSS features are extensionspecific, it is recommended that all DPNSS

lines be configured as Auto-answer lines.

• The Page feature is available to both remote callers and callers within the

system.The operation ofthe feature is identical, however the remotecaller must

have DTMF capability to access the feature.

• Line Redirection allows the originating party to redirect a call, waiting a

connection or re-connection, to an alternate destination after a time-out period.

Failed calls can be redirected. Priority calls cannot be redirected.
