Required Hardware
Table 1-1 lists the required equipment for standard, high, critical reliability, and
ATM network duplication configurations.
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 Jack

(comcode 10798867)
■ 103A block
■ 1541CC cable kit

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

T1 or E1 synchronization splitter

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).
