Introduction
MP2100M-LS-2 Modules - Installation and Operation Manual 1-5
/SDM modules can provide up to twenty 2.4 kbps
channels. Other combinations of channel numbers and
data rates are allowable (see Section 1.2).
LS-2 Modules
The LS-2 modules include three versions of modules, identified by /X.50,
/X.58, and /SDM. The LS-2 modules are similar in characteristics to the
MTLS-2 and LS-2A modules described above, except that they support only
synchronous operation.
MTLS-2/2TS and LS-2A/2TS Modules
Figure 1-4 shows a typical application for the MTLS-2/2TS and LS-2A/2TS
modules.

Figure 1-4. Typical Application for MTLS-2/2TS and LS-2A/2TS Modules
The MTLS-2/2TS and LS-2A/2TS modules use a sub-multiplexing technique
compatible with ITU-T Rec. X.50, Division 3, and ITU-T Rec. X.54 to provide
two fixed functions:
• Transmission of ten synchronous or asynchronous 9.6 kbps channels.
Channels 1 through 5 are transmitted as one group in one main link time
slot, and channels 6 through 10 are transmitted as one group in another
main link time slot.
