1.2. Voice Hardware Covered by This Manual

• 1.2.1. Voice Hardware Model Names

The D/42 Series voice hardware (also referred to as D/42-xx) is designed to provide a set of cost-effective tools for implementing computerized, voice and call processing applications for private branch exchange (PBX) systems and key telephone systems (KTSs). It provides the basic voice and call processing capabilities of D/4x voice hardware and adds hardware and firmware required to integrate with PBXs and KTSs. Refer to the Voice Software Reference for more information on voice and call processing. For convenience, the terms private branch exchange (PBX), key system unit (KSU), and key telephone system (KTS) will be referred to as PBX.

The voice hardware models covered by this manual include the following:

NOTE:

Although the D/42D-SX and D/42D-SL boards are documented in this manual, they are not supported in this release.

D/42D-SXTM -- a 4-channel voice board with station interfaces for connecting directly to a MITEL^® SUPERSET 4TM Line Circuit card in a MITEL SUPERSWITCH^® PBX.

D/42D-SLTM -- a 4-channel voice board with station interfaces for connecting to a Northern Telecom Digit Display (QPC 451 or QPC 61) Line Circuit card in a Northern Telecom SL-1 PBX.

D/42-NSTM -- a 4-channel voice board with station interfaces for connecting to a Northern Telecom NORSTAR^® key system unit (KSU).

D/42-NE2TM -- a 4-channel voice board with digital interfaces for connecting to NEC Electra Professional Level II telephone systems, as well as NEAX^© 2000 IVS and NEAX 2400 IMS PBX series switches. Throughout this manual, the NEC Electra Professional Level II is referred to as the NEC KTS, while the NEAX^© 2000 IVS and NEAX 2400 IMS are referred to as the NEC PBX.


1.2.1. Voice Hardware Model Names

Model names for voice boards other than the DIALOG/HD series are based upon the following pattern:

D / x x x y 

where:

D/ identifies the board as voice hardware

xxx identifies the number of channels (2, 4, 8, 12, etc.), followed by a code indicating whether Call Progress Analysis is supported

0 indicates no support for Call Progress Analysis

1 indicates support for Call Progress Analysis

2 indicates PBX support

y if present, identifies a hardware version (A, B, C, D, etc.)

Sometimes it is necessary to refer to a group of voice boards rather than specific models, in which case an "x" is used to replace the part of the model name that is generic. For example, D/xxx refers to all models of the voice hardware, and D/4x refers to all 4-channel models.
