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.
