De Avaya IP500 Expansion Module beschikt over 30 poorten voor
het aansluiten van digitale telefoons.
All expansion modules are supplied with a base software level and should be upgraded to match the core software of the control unit in the IP Office system. Expansion modules include an external power supply unit (PSU) and an appropriate interconnect cable. They do not include a locale specific power cord for the external PSU or any phone extension cables.
This IP Office ATM-4 daughter card can be added to an IP500 DS8 card,
IP500 Analogue Phone (2 or 8 port) card, or IP500 VCM card.
It then allows that card to also support 4 analogue loop-start trunks.
This card also provides 1 analogue V.32 modem. Not compatible with the IP412.
IP500 daughter trunk cards can be fitted to existing IP500 base cards to provide support for trunk ports.
The daughter card uses the ports provided on the base card for cable connection.
The addition of an IP500 daughter trunk card is supported
on IP500 Digital Station, IP500 Analogue Phone and IP500 VCM base cards.
For those base cards that support daughter cards, there are no restrictions
on the combination of card types.
However in systems with both Analogue Phone 8 base cards
and analogue trunk daughter cards, combining both types is recommended
as it then provides analogue power failure support for 1 trunk or extension
(Not applicable to the Analogue Phone 2 base card).
