Chapter 1 General Information MX-2100/2104 Installation and Operation Manual
1-12 Physical Description
Option Modules (not for MX-2104)
The 3U MX-2100 system can accept two types of options module:
KAI
Alarm indication module for installation in the options position, or in any I/O slot.
The KAI includes indicators similar to those located on the MX-2100 front panel.
These indicators repeat all the relevant MX-2100 front panel indications on the
rear panel, and thus complement the indicators available on the rear panels of the
other modules. Maintenance activities are thus expedited, as all the MX-2100
indications become readily available on one side of the equipment.
KDI
Bypass and multidrop module. The KDI module can be installed in the option slot,
or in any I/O slot. The KDI module enables direct transfer (bypassing) of a group of
main link frame bits, in both directions, between the two main links of MX-2100.
Channels that are not bypassed are connected to I/O modules of MX-2100.
The KDI module is available in two versions:
KDI version: supports only the bypassing function
KDI/M version: also includes a data channel interface for one multidrop channel.
The multidrop channel is compatible with the data channels of the KLS.1/NEW
low-speed data module, and supports data rates in the range of 0.3 to 64 kbps. As
is standard practice in a multidrop application, the receive path of the local
multidrop channel continuously receives the data transferred in its allocated
bandwidth on the desired main link (the same data is also bypassed to the other
link, to make it available downstream), but its transmit path is connected to the
main link only when the RTS line in the local interface is asserted.
For more information, see the option module’s Installation and Operation Manual.
I/O Modules
MX-2100 supports up to 12 user-selected I/O modules. MX-2104 supports up to 4
user-selected I/O modules. Both units can accept any combination of the following
types of I/O modules with power supply limitations.
KVC.1 - ADPCM or PCM voice interface module, provides two voice channels. For
more information, refer to the KVC.1 Installation and Operation Manual.
The following versions are available:
KVC.1/E&M: four-wire or two-wire interface with E&M signaling per
RS-464 Types I, II, III and V, and British Telecom SSDC5
KVC.1/FXS: two-wire interface for direct connection to a telephone set
KVC.1/FXO: two-wire interface for direct connection to a PBX extension
line.
