The Avaya IP500 Analog Trunk 16 Module (700449473) expansion module provides an additional sixteen Loop Start or Ground Start two-wire analog trunks. (Ground start trunks are not available in all territories).
The first two trunks on the module which are automatically switched to power fail sockets on the rear of the unit in the event of power being interrupted must be loop start for correct power fail operation.
For installations in a rack, this module requires the IP500 Rack Mounting Kit. The IP500 Analog Trunk 16 Module is functionally identical to the IP400 Analog Trunk 16 Module.
*Note: Ground start trunks are not available in all territories.
This module is compatible with the current IP500 Avaya IP Office system.
