Chapter 1. Introduction

OPTION SLOT ARRANGEMENT

As viewed from the rear of the TSU 600, the slots are numbered as shown in Figure 1-4. All slots are functionally identical except slots one and six. These slots offer additional functions.

Slot 1

Slot 1 is used as the source of DTE timing when the DTE timing mode is selected. If DTE timing is de- sired, the DTE interface port sourcing the timing must be connected to Slot 1. This slot will accept all other interface types except Secondary Network interface option modules, including DSX-1 (PBX), the Full Drop and Insert (D&I) network interface, or the Dial Backup (DBU).

Slot 2

Slot 2 is used for the Dial Backup module if a DBU is installed. This slot accepts all other interface types except Secondary Network interface option modules, including DSX-1 (PBX) and the Full Drop and Insert (D&I) network interface.

Slots 3-5

Slots 3-5 will accept any interface type except second- ary interface, the interface for DTE timing, or the DBU. If other interfaces have any restriction on their loca- tion, this will be specified in the individual option card manual (provided with the option cards).
