The ATLAS 550 provides two Network Interface Slots that allow different
types of interfaces to be used. Currently only a T1 Network Interface is avail-
able. In the remainder of this manual, discussions about the Network Inter-
face Module refer to the T1 Network Interface Module. The T1 Network
Interface (NI) port complies with the applicable ANSI and AT&T
dards. The T1 Network Interface Module provides the following functions:
• AMI or B8ZS coding
• Manual line build-out
• D4 or ESF framing
• Network performance monitoring and reporting
• Test loopbacks with QRSS generation and checking
• Extensive self-testing
The network connections follow, with the pinouts shown in Table 2-6 and
Table 2-7 on page 2-8.
