CSU/NIU Emulation This mode places the test set in a CSU/NIU configuration and the
test set will respond to CSU or NIU loopback and loop the recovered receive data to
the transmit back towards the network.
DS2 STATUS
–
Select this mode to monitor and test one
of the seven DS2’s. The top
screen is the receive DS2 1-7 and the bottom screen is the transmit DS2 1-7. The test
set
monitors and transmits RAI, AIS and LOF from all seven DS2’s.
DS1 Drop
– Select this mode to monitor or Drop any 1 of the 28 DS1’s within the DS3.
DS3-DS1-DS0 systems can drop a DS1 to the DS1-B port. From the main DS3 screen
you can select T1 by pressing on DS3 button and select DS1-A or B to go straight to
the DS1 test interface.
DS3 Thru Mode
–
Select this mode for intrusive through-mode testing. Through-mode
gives you the ability to place the test set in series with a RCV or XMT pair for monitor-
ing errors and alarms. The test set receive recovers the DS3 signal and passes it to
the transmit circuitry; framing and signal format is regenerated.
DS3 Thru Mode No GEN
– Select this mode for intrusive through-mode testing with
framing and signal format passing directly through to the transmit circuitry without re-
generating framing errors, BPV, alarms, etc. Any error detected on the RCV pair will
be passed through to the XMT pair. The test set still captures and display all received
errors.
Clocking
The test set default clocking is NW-Network (recovered) clock. In TERM mode only
Int-
Internal clock may be selected by pressing NW Network button and select Int-Internal
clock. The test set will now be the master clock.
Framing Selection
The test set
default framing is ‘C-Bit’. To change the framing press C-Bit and select
M13, Unframed or Auto. In Auto framing, the occurrence of an LOS greater than two
(2) seconds will trigger an Auto-frame upon next valid signal (pulse) detection.
