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).
Analog Trunks
Loop Start
·
Loop start trunks are available on the IP Office Analog Trunk cards installed within the IP Office control
unit, or on the Analog Trunk 16-port expansion modules (ATM16). The first two trunks on the ATM16
are automatically switched to power fail sockets in the event of power being interrupted. They conform
to the TIA/EIA-646-B standard. The loop start trunks also support incoming caller line identification
(ICLID) conforming to GR-188-CORE and GR-31-CORE standards. IP Office can use this information to
route calls or provide it to computer applications to display additional information about the caller.
Ground Start
·
Ground Start trunks are only available on the ATM16, configured through IP Office Manager. The first
two trunks on the module are automatically switched to power fail socket in the event of power being
interrupted. They conform to ANSI T1.401 and TIA/EIA-646-B standards. Not available in all territories.
