CHAPTER

Installation - Subtended Network

This section discusses installation procedures for adding subtended 6100s to a subtending host 6100.
In this manual, the term “subtending” refers to the host 6100 node, and “subtended” refers to the
downstream 6100 node in a subtended network.

All 6100s in a subtended network are installed in either a Digital Off-Hook (DOH) or a direct
connect configuration first. Then if the network is to be subtended, the procedures in this section
apply.

8.1.1 Cable Diagram - Subtending

The following is an illustration of the basic cabling of a subtended 6100. Some connectors are not
used because they are specific to one of the other configurations of the 6100 or because they have
been reserved for future use.

8.1.2 Cable Type - Subtending

The DS3 subtending I/O card on the subtending host 6100 connects directly to the system
I/O card on the subtended mode 6100. This connection is made with DS3 75-ohm coaxial cable.

subsections, as noted in the last column of the Table 8-1, discuss each of the installation steps in
detail.

Table 8-1 Installation Steps Checklist
Check Installation Step

1. Install each of the Cisco 6100s in the system, including the subtended ones, with either DOH or direct
connect configuration as described in previous sections

2. Connect the DS3 subtending card to the MC backplane

3. Install the 2x DS3 subtending host module (STM) in slot 9 of the subtending host 6100 and the DS3
NI module in slot 10 of the subtended node MC

4. Cable the DS3 subtending I/O card on the subtending host MC to the system I/O card on the subtended

node MC

5. Complete the installation as described in the previous chapters, provision and test

NI=network interface

8.2.1 Installing the 6100s

Before connecting the subtended node 6100s to the subtending host 6100, install and cable all the
6100s, including the subtended ones, according to the procedures described in Chapters 5, 6, and 7
of this manual. Subtending is independent of the configuration style used. It works with both DOH
and direct connect.

8.2.2 Connecting the DS3 Subtending Card

The DS3 subtending I/O card has two sets of DS3 75-ohm coaxial BNC connectors. Each set
consists of a transmit and a receive connector. The following figure illustrates the 2x DS3 subtend
card.
