Understanding the DPA 7630/7610
The Cisco DPA 7630/7610 enables you to integrate your existing Octel voice mail
with Cisco CallManager and either a Definity PBX system or a Meridian 1 PBX
system. If you have a Definity PBX, use the DPA 7630; if you have a Meridian 1
system, use the DPA 7610.
The DPA 7630/7610 functions as a gateway between the Octel, PBX systems, and
Cisco CallManager, performing these tasks:
•
Determines the call type from Cisco CallManager and sends envelope
(display), light, and ring messages to the Octel system.
•
Determines when the Octel system is attempting to transfer, outcall, set
message waiting indicators (MWI) and so on, and sends the appropriate
messages to Cisco CallManager.
•
Converts Dual-Tone Multi-Frequency (DTMF) tones to Skinny Client
Control Protocol (SCCP) messages.
•
Converts Nortel Display Key commands to Skinny Client Control Protocol
(SCCP) messages
•
Provides companding-law transcoding, and voice compression.
•
Performs Real-Time Transport (RTP) encapsulation of the voice message.
These sections provide additional detail about the interfaces and supported
protocols on the DPA 7630/7610:

DPA 7630/7610 Physical Description
The DPA 7630/7610 is a 19-inch, rack-mountable hardware device capable of
emulating digital telephones or digital PBX ports. By emulating these devices, the
DPA 7630/7610 enables you to integrate Cisco CallManager with existing Octel
voice mail systems and Definity or Meridian 1 PBX systems.
The wiring and external connectors of the DPA 7630 and the DPA 7610 differ
slightly because the Definity system uses a 4-wire wiring scheme, and the
Meridian 1 system uses a 2-wire wiring scheme.
