Specifications

OAS (OPTIONAL APPLICATION SERVICES)
The OAS card provides 64 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 by 16. In addition to these config-
urable 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 in any cabinet. If installed in an expansion cabinet, however, the
number of configurable DSP’s is reduced to 32 due to the timeslot restrictions in expansion cabinets. A maximum
of 32 OAS cards can be installed, allowing up to 256 Executive MOBEX users, 512 MGI channels, or a mixture of
each, and up to 512 MPS channels.
Note: Executive MOBEX is a licensed feature. See Mobile Extension (MOBEX) for more information.
2.3.3 STATION CARDS
8DLI2
This card is an eight circuit digital station interface card that provides 2B+D service when installed in any univer-
sal card slot in all cabinets. Keyset daughter boards will only work when connected to this card.
16DLI2
This card is a sixteen circuit digital station interface card that provides 1B+D service when installed in any univer-
sal card slot in all cabinets. Keyset daughter boards will not work when connected to this card.
8SLI3
This card is a eight circuit analog station interface for industry standard single line telephones or other analog
peripheral devices. The 8SLI does not contain any over-voltage protection and is not qualified as OPX. This card
automatically detects DTMF or dial pulse signals from the SLT ports. Each port on this card has built-in DTMF
receivers (for DTMF tone detections from analog devices) and CID transmitters (sends FSK signals for displaying
CID name and number to analog devices). The 8SLI3 does not need to share these system resources. This will
relieve the congestion of the MFM, RCM2, or CRM system resources. It can be inserted in any universal card slot in
all cabinets. Each port on this card is intended for connection to one telephone. Connecting multiple telephones
to a port may result in incorrect operation or damage to the card. The 8SLI3 supports message waiting lamp func-
tionality for analog stations that have this capability. This card supports Power Fail Transfer feature. See the instal-
lation manual for details. (This card requires software version 4.60 or higher).
16SLI3
This card is a sixteen circuit analog station interface for industry standard single line telephones that require oper-
ation of an industry standard message waiting lamp with a voltage range of 85~96 VDC. The lamp can flash at a
rate of 100ms to 200ms ON/OFF times. The 16SLI3 does not contain any over-voltage protection and is not qual-
ified as OPX. This card provides sixteen ports of connecting analog stations. It can go into any universal slot of any
cabinet. Add as many as needed. This card automatically detects DTMF or dial pulse signals from the SLT. Each port
on this card has built-in DTMF receivers
(for DTMF tone detections from analog devices) and CID transmitters
(sends FSK signals for displaying CID name and number to analog devices). The 16SLI3 do not need to share these
system resources. This will relieve the congestion of the MFM. RCM2 or CRM system resources. It can be inserted
in any universal card slot in all cabinets. Each port on this card is intended for connection to one telephone.
Connecting multiple telephones to a port may result in incorrect operation or damage to the card. The 16SLI3
supports message waiting lamp
functionality for analog stations that have this capability. This card supports the
Power Fail Transfer feature. See installation manual for details. (This card requires software version 4.60 or higher).
