40 DS1 Configuration
on the Monitor button and selecting the desired test. In the example below the test set
is configured as TERM, NW Clock, ESF Framing, B8ZS Coding, and BERT-Off.
DS1 Auto Configuration
The test set is capable of determining the proper signal and framing detected on a live
circuit and self configuring itself to achieve signal lock and pattern synch. This makes
configuration fast and easy. To enable select
Auto from the framing drop-down menu.
The test set will auto-detect and configure the framing, coding and BERT pattern de-
tected on the received signal.
Note: if an all-
1’s pattern or a fixed pattern with a high 1’s density is received, the test
set will not be able to auto-detect B8ZS coding. A BERT pattern such as QRSS or
3in24, etc. must be received in order to properly detect B8ZS coding.
DS1 Mode Selection
In the mode selection drop down are the following options:
Monitor
–
Select this mode if monitoring at a DSX (
–20dB) point or at a monitor port on
smart jacks (NIU). The transmitter is off when in MONITOR mode.
TERM DSX
–
Select this mode to perform intrusive testing, e.g. send loopbacks,
straight away BERT tests, etc. tap on DS1 TERM DSX and select a clock mode:
looped NW (recovered) or internal INT (master).
Bridged
–
Select this mode for monitoring at a high impedance point. The receiver is
placed in a >1K
Ω high impedance state for monitoring RX or TX lines. The transmitter
is off when in BRIDGED mode.
