PCM highway is any time-division multiplexed serial interface (i.e., data is transferred over
time slots). The most common examples of a PCM highway (serial bus) are a T1 line or a
CEPT line; however, there are many other possible PCM highway configurations. T1 has 24
8-bit channels and is clocked at 1.544 MHz. CEPT has 32 8-bit channels and is clocked at
2.048 MHz. In both cases, the actual rate of an 8-bit channel is 64 kbps. If more data
throughput is needed, multiple 8-bit time slots can be grouped together for faster data trans-
fer. You may wish to choose PCM highway, even if you only have one SCC using the inter-
face (and therefore one long time slot) as will be shown.
Example 1. If you need multiple transparent channels on separate physical interfaces, then
all of them can be NMSI or all but one as NMSI. Thus, you can choose from the following
four combinations:
MOTOROLA
The following examples illustrate how the different types of interfaces can be combined.
1. NMSI1, NMSI2, and NMSI3
2. PCM, NMSI2, and NMSI3
3. IDL, NMSI2, and NMSI3
4. GCI, NMSI2, and NMSI3
