North American T1

Provided by the IP400 PRI T1 and IP500 Universal PRI cards.

T1 Primary Rate provides up to 24 64K channels over a 1.54M circuit. Each channel of the T1 trunk can be

independently configured (channelized) to support the following signaling emulations with handshake types of

immediate, delay or wink.

· Loop-Start

· Ground-Start

· E&M Tie Line

· E&M DID

· E&M Switched 56K

· DID - Channels configured for DID/DDI support incoming calls only. The carrier or Central Office will

provide the last x digits that were dialed to be used for call routing.

· Wink-Start

IP Office T1 trunks support both DNIS and ANI services, where available from the central office.

· Dialed Number Identification String (DNIS) Provides a string of digits to the IP Office depending on the

number dialed by the incoming caller. This string can then be used to route callers to individual

extensions, groups or services.

· Automatic Number Identification (ANI) Provides IP Office with a number identifying who the caller is.

This may then be used for routing or computer telephony applications.

T1 trunk cards incorporate an integral CSU/DSU, eliminating the need for an external unit. The CSU function

allows the trunk to be put in loop-back mode for testing purposes. This can be set manually, using the monitor

application, or automatically from a Central Office sending a Line Loop Back (LLB) pattern. The DSU function

allows the T1 trunk to be shared between data and voice services.

North American Primary Rate Interface

Provided by the IP400 PRI T1 and IP500 Universal PRI cards.

IP Office supports Primary Rate ISDN trunks on 5ESS or DMS100 central office switches provided by AT&T,

Sprint, WorldCom and other Local Telcos. Channels can be pre-configured for the supported services or

negotiated on a call-by-call basis.

Special Services can be configured to route calls to local operators or pre-subscribed carriers for both national

and international calls (SSS). Alternate carriers can also be selected through the configuration of IP Offices

Transit Network Selection (TNS) tables.

IP Office also supports the Calling Name and Number service over Primary Rate Trunks (NI2).
