Chapter 1 General Information MX-2100/2104 Installation and Operation Manual

1-14 Physical Description

• KHS.U - Data interface module, provides one or two ISDN basic access rate

type "U" interfaces. The KHS.U module enables the extension of ISDN lines

over non-ISDN facilities. For more information, refer to the KHS.U Installation

and Operation Manual.

The following versions are available:

− KHS.U/S with one "U" interface

− KHS.U/D with two "U" interfaces.

• KHS.703 – High-speed data module that provides two independent 64 kbps

codirectional data channels per ITU-T Rec. G.703. Each module is terminated

with an RJ-45 eight pin connector. For more information, refer to the KHS.703

Installation and Operation Guide, further on in this manual.

• KVF.4 - Voice/fax relay module using advanced digital signal processing (DSP)

techniques (MPMLQ in accordance with ITU-T Rec. G.723.1) to provide one

or two channels for transmission of voice and standard Group III fax signals

over the MX-2100 link with automatic switch-over between voice and fax

modes. For more information, refer to the KVF.4 Installation and Operation

Manual.

The following versions are available:

− KVF.4/E&M: two channels with four-wire or two-wire interface with E&M

signaling per RS-464 Types I, II, III and V, and British Telecom SSDC5

− KVF.4/E&M/E: similar to the KVF.4/E&M, except that it requires an external

-48 VDC source to supply the signaling voltage for increasing the maximum

allowed line length

− KVF.4/FXS: two voice channels with two-wire interface for direct

connection to a telephone set

− KVF.4/FXS3: similar to KVF.4/FXS, except that it supports pulse metering

and polarity reversal

− KVF.4/FXSP: similar to KVF.4/FXS, except that it has an internal ringer and

line feed supply

− KVF.4/FXSW: one channel similar to the channels of the KVF.4/FXS, and

one two-wire interface operating with FXO signaling, intended for

connection to the PSTN, or to a PBX extension line

− KVF.4/FXO: two channels with two-wire interface and FXO loop start

signaling for direct connection to a PBX extension line

− KVF.4/FXO3: similar to KVF.4/FXO, except that it supports pulse metering

and polarity reversal

− KVF.4/S0: one ISDN basic rate access type "S" interface for direct

connection to an ISDN PBX.
