channels, a group of two /X.58 modules can provide
up to twelve 4.8 kbps channels, and a group of four
/X.58 modules can provide up to twenty-four 2.4 kbps
channels. The allowable combinations of channel
numbers and data rates are explained in Section 1.2.
Figure 1-2 shows a typical application for
MTLS-2/X.58 modules.

MTLS-2/SDM, These modules use a sub-multiplexing technique
LS-2A/SDM compatible with AT&T Pub. 54075 (DS0-B format).
This technique supports a maximum payload similar
to that specified by ITU-T Rec. X.50, Division 3, that
is 48 kbps.
Figure 1-3 shows a typical application for
MTLS-2/SDM modules.

Figure 1-3. Typical Application for MTLS-2/SDM Modules
An MTLS-2/SDM or LS-2A/SDM module has ten
channel interfaces, and two modules can be operated as
one group to allow the transmission of twenty channels
in one main link time slot. One /SDM module can
provide up to ten 4.8 kbps channels, and a group of two
