SWITCH (OR CUSTOMER) REQUIREMENTS FOR DCP MODE 1

To implement AUDIX networking over static or dynamic switched 56 Kbps facilities, the customer’s switch must have a DCP interface to connect with the AUDIX system and a DS1 interface to connect with the 56 Kbps switched network.

Whether a customer is using static or dynamic 56 Kbps, the point-of-presence switch needs to be translated to match the switch, (including wink in/wink out). The RNXs are set up by the customer and added to the network by Network Systems.

NOTE

Contact the Business Communications Systems Design Center (BCSDC) to design ISDN.

The following equipment is typical for 56 Kbps facility access:

∙Digital Line Circuits for the AUDIX network

∙DS1 Interface

∙For R1V5 or R1V6, a Modular Processor Data Module, Model M1* (MPDM/M1*) ACCUNET data module with V.35 interface card (for loopback testing)

NOTE

See the DEFINITY® Communications System & System 75/85 DS1/DMI/ISDN-PRI Reference (555-025-101) for a complete specification of requirements.

Static Access Switch Requirements

The requirements for networking AUDIX systems via static 56 Kbps facilities depend on the customer’s premise switch:

∙System 75

—The switch must be R1V3 2.1 or later.

—All tone detectors must be TN748C (V4 or later).

∙DEFINITY Generic 1 and Generic 3

—Any release will support static 56 Kbps access.

—All tone detectors must be TN748C (V4 or later).
