In a single 4 lb (1.8 kg) package, the 635 includes all the basic T1
testing capabilities you would expect in a larger and more expensive
tester. It performs bit-error tests, detects framing type, line
coding and bit pattern, and displays signal level, frequency, clock
slips, errors and alarms. The 635 transmits the most commonly used
loop codes, including HDSL. Full, unframed and fractional (56k and
64k) T1 are supported, along with display of signaling and data bits
and capture of DTMF digits. Plus, individual voice channels may be
monitored on the built-in speaker or over a headset.
Eleven standard BERT patterns are available, including a 64-bit
user-defined pattern. The 635 also includes a "through" mode where
the incoming pattern is retransmitted. Errors - including bipolar
violations, logic and frame bit - can be injected to confirm proper
handling by the network. Two receivers permit detection of any clock
slips. Multiple receiver input types allow terminated, bridged or
monitor (DSX) connections. Either recovered or internal clock
references can be selected. AMI or B8ZS line coding can be
transmitted and received, and SF, ESF, SLC96 and unframed framing
are supported.
The 635 is compact, rugged and easy to use. Just plug it in and you
can immediately see essential information without scrolling through
layers of menus. The 635 automatically detects framing and line
coding type and instantly displays any errors or alarms. A history
indicator helps track intermittent problems. |
