Extensive Testing Capability. Provides the capability to maintain the T1
access unit and diagnose device and network problems via:
—
Menu-Driven User Interface. Accessed using an async (or other
VT100-compatible) terminal, PC emulation, or Telnet, provides T1
network, DSX-1, sync data port, voice port, and device (lamp) tests.
Loopbacks that can be selected for an interface include: line, payload,
repeater, remote line, DTE, DTE payload (V.54 loop 3), data channel,
remote data channel (V.54 loop 2 or FT1), V.54, digital, and analog.
Pattern Tests that can be selected for an interface include: QRSS,
all zeros, all ones, 1-in-8 (T1 interface only), 3-in-24 (T1 interface only),
63, 511, 2047, 2

-1, 2

-1, and 2-byte (user defined).
Tone and signal tests can also be selected for voice APMs.
—
SNMP MIB Object Test Commands. Supports the same testing capability
as the user interface.
Appendix B
provides a complete user interface-
to-MIB object cross-reference.
—
Test Jacks. Located on the T1 access unit’s faceplate, support using
external test equipment to perform break-in testing and monitoring of the
T1 network and DSX-1 interfaces. Remove the housing’s bezel to access
these jacks.
Extensive Monitoring Capability. Provides status information to help you
keep track of and evaluate the unit’s and network’s operation via:
—
Status Branch. Provides system and test status, voice card status for all
eight ports for each card, channel status for all DS0 assignments for all
time slots of the T1 network interface, channel status for all DS0
assignments for all time slots of the DSX-1 interface, and all port
assignments for each voice and data port of both the NAM and APM
cards.
—
Front Panel. Provides test jacks to monitor the unit’s T1 network and
DSX-1 interfaces, and LEDs to monitor the unit and its interfaces.
Test jacks. Accessed by removing the housing’s bezel, provide T1
network and DSX-1 monitoring.
LEDs. Visible without removing the bezel, provide unit and interface
monitoring that includes T1 network and DSX-1 interface received signal
status, as well as synchronous data port statuses.
