The Total Access 850
system provides a single T1 port (located on the rear panel) and complies with the
applicable ANSI and AT&T™ standards. The T1 interface provides the following functions:
•
AMI or B8ZS
•
Manual line build-out
•
D4 or ESF framing
•
Network performance monitoring and reporting
•
Test loopbacks with QRSS generation checking
•
Extensive self-testing
The T1 connection pinout is shown in Table 12.
Table 12. Network Connection Pinout
DSX-1 Connection (JP3)
The Total Access 850 system provides a single DSX-1 port (located in the rear of the unit). The DSX-1
interface provides the following functions:
•
AMI or B8ZS
•
Manual line build-out
•
D4 or ESF framing
The Total Access 850 provides dual T1 connection points. In all cases, only one of
the connection points is used. When wire-wrapping of the T1 is utilized (using P3), a
blank plug must be placed in the primary T1 connection (JP2). There is a potential of
Class A3 T1 Span Power Voltage coming from the network.
