This type of card is used to add voice compression channels to the control unit. Those channels are used for VoIP calls including IP extensions and or IP trunks. IP500 V2 control units support up to 148 voice compression channels, using IP500 VCM cards and IP500 Combination Cards.

The cards are available in 32 channel and 64 channel variants. All the card variants have 4 RJ45 ports which are used for trunk connections when an IP500 trunk daughter card is fitted. V2 and V3 VCM cards are identical in supported features and functionality except for minimum supported IP Office version (see below).

•Supports
Codecs G.711, G.722, G.729ab, and G.723 with 64ms echo cancellation. The maximum number of channels useable is affected by the codec used. The following table assumes all calls use the same codec. Note: G729b is not supported by Linux-based IP Office systems.

Features

Not present

1 to 8

•LEDs 1 to 8 are unlabelled. They are used to indicate voice compression channel usage. Each LED represents 12.5% of available voice compression channel capacity.

•LED1 is also used for base card status:

•Red On = Error/Not supported.

•Red Slow Flash = Initializing.

•Red Flash every 5 seconds = Card okay.

•Red Fast Flash = System shutdown.

Optional Trunk Card Ports

9 to 12

The card can be fitted with one trunk daughter card of any type. The trunk daughter card then uses ports 9 to 12 on the base card for its trunk connections.

LED use depends on the type of daughter card installed on the base card:

•LED 9 is also used for daughter card status.

•Red On = Error

•Red Slow Flash = Initializing.

•Red Flash every 5 seconds = Card okay.

•Red Fast Flash = System shutdown.

Analog Card

•Green on = Line connected to the port but idle.

•Green flashing = Line in use.

PRI Card

•Off = No trunk present.

•Green on = Trunk present.

•Green flashing = Trunk in use.

•Red/Green Fast Flash (port 9) or Green Fast Flash (port 10) = Alarm indication signal (AIS) from the trunk remote end.

•Red with Green Blink (port 9) or Green Blink (port 10) = Port in loopback mode (set through IP Office System Monitor).

 

BRI Card

•Off = No trunk present.

•Green on = Trunk present.

•Green flashing = Trunk in use.
