OAS (OPTIONAL APPLICATION SERVICES)
The OAS card provides 32 digital signal processors (DSP's) that can be configured as MGI channels, MOBEX DTMF
receivers used by the Executive MOBEX feature, or a mix of the two. MGI channels are enabled in 4 port incre-
ments, and each increment will decrease the available MOBEX DTMF receivers. In addition to these configurable
DSP's the OAS card provides 32 DSP's dedicated to providing 64 Media Proxy Service (MPS) channels. The OAS
card can be installed in any universal slot. When installed in slot 1 or 2 of the main cabinet or slots 1, 2, 4 or 5 of
the expansion cabinet only 16 timeslots are available for the OAS card, so a maximum of 16 MOBEX DTMF
receivers per card is possible. All other slots allow up to 32 MOBEX receivers per card. A maximum of 5 OAS cards
can be installed, allowing up to 64 Executive MOBEX users, 80 MGI channels, or a mixture of each, and up to 256
MPS channels.
