Section 2 – Functional Design

This section explains the functions of the ACS-160 and STL-160 Series multiplexer components and
describes how to use the multiplexers to configure both point-to-point and drop and insert T1
systems.

2.1 Component Functionality

2.1.1

Main Equipment Shelf and Midplane

All modules, module adapters, and power supplies plug into the main equipment shelf. These
components communicate with each other via the shelf midplane (or motherboard), which contains
both signal and power distribution buses (Figure 2-1).

Figure 2-1. Midplane Connections

Note:

The ACS-166 and ACS-169

Dual Terminal

Access Servers use different midplanes from those

used in the ACS-163 Terminal Access Server, ACS-165 Drop and Insert Access Server, ACS-
168 Drop and Insert Access Server,

STL-163 Studio-to-Transmitter Link, and STL-165 Studio-

to-Transmitter Link multiplexers. It is not possible to use these five multiplexers as

dual

terminal

access servers.

Power enters at either the AC or battery connectors and passes to the power supply. The power supply
provides three voltages to the power distribution bus (+5 VDC, +15 VDC, and -15 VDC), from which
each common and channel module draws current as needed. Power supplies from the signaling battery
and ring generator, if used, also connect to the power distribution bus.
