Avaya IP Office
IP 400 Office Quad Analog Trunk Card
Provides four Analog trunk 2 wire interfaces (loop start only) including support for caller ID.
Ground start analog trunks are supported via the IP Office Analog Trunk 16 Expansion Module.
Loop start trunks are available on the IP office as 4-port plug in cards for the base unit or as a stackable 16-port module.
The first two trunks on the stackable module 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 (Not available in all territories)
Ground Start trunks are available as a stackable 16-port module. See Section 2 for detail. 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.
