Required Hardware

Table 1-1 lists the required equipment for standard, high, critical reliability, and

ATM network duplication configurations.

1.TN2305 (multimode fiber); TN2306 (single-mode fiber) for Release 8 ATM-PNC.

2.High reliability requires 2 ATM-EI circuit packs in the PPN and 1 ATM-EI in each EPN.

3.The number and uses of the synchronization splitter depend on the configuration and the source(s) from which primary and secondary synchronization is derived. You may need 1 sync splitter per ATM switch. DS1 synchronization requires either no sync splitter or up to a number twice the number of sites.

4.Existing fiber optic cable may require an ST-to-SC adapter, depending on the interface at the ATM switch. The TN2305/TN2306 circuit pack requires an SC connector (1 adapter is included in the Fiber Pass-Through Kit).

5.For network duplication; required for systems supporting PRI, BRI, or ASAI.

To test the synchronization splitters, you need the following equipment:

■Phoenix 1541C Test Set with accessory cord kit

■Phoenix 5575A T1 Test Set with cord kit or equivalent

■700A DS1 CPE Loopback Jack1 (comcode 10798867)

■103A block

■1541CC cable kit
