Required Hardware
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

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.
