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.
