User
Description
Clear
Clear
Terminates operator or externally-initiated Loopbacks,
BERT, and Test Packet tests.
Line Lp to Netw
Sets a Line Loopback at the T1 interface toward the
Network.
Payld Lp to Netw
Sets a Payload Loopback in the CSU toward the Network.
User Lp to Netw
Loops the User Port back toward the Network.
Send LoopUp
or
Send LoopDn
Transmits T1 Line Loop Up or Line Loop Down code
toward the Network.
QRSS to Netw
Alt Ones to Netw
2047 to Netw
Zero to Netw
Directs the indicated Full T1 BERT Pattern toward the
Network.
User 2047 to Netw
User Zero to Netw
Directs the indicated BERT Pattern toward the Network
Circuit (for DS0s assigned to the User Port.)
Loop to User
Loops data back to User Port.
2047 to User
Directs the indicated BERT Pattern toward the User Circuit.
Line Lp to CPE
Full T1 Line Loopback applied within the unit’s framer
toward the CPE port(s): User Port (also DSX Port and Drop
Port if DSX/Drop Adapter installed.)
Test Pkts to New
Sends Link Test Packets (40 -1590 octets) toward the
Network (T1 Facility).
NOTES:
1. All User Port Loops and BERTs are at the current User Port configured data rate (56 or 64 kBps.)
2. Only one BERT may be active at a time. The results are a count of the number of Blocks Sent,
Blocks Errored, Block Error Rate and the duration of the test, displayed as shown on the example
screen above. When the BERT duration reaches the maximum count of 99:59:59, all counts freeze
until cleared or reset by the operator (the BERT data however, continues to be sent).
3. PVC tests will prompt for the input of a PVC DLCI destination.
4. Test Pkts to Netw display results include selected DLCI, packets sent, packets dropped, percent
received, octets sent, test duration and average and maximum delay (network and full delay), for
each network segment.This test’s delay values may not correlate to values displayed on the PVC
Statistics Screens because the Link Test Packet size (40 - 1590 octets) is larger than the Delay
measurement packet (36 octets).
5. Delay and Loss measurement packets (for ALL PVCs) are halted, while a “Test Pkts to Netw” test is
performed. This will also affect the Delay and Loss packet counts and measurement fields on the
PVC Statistics Screens.
6. Initiating certain test options, when management access is via the T1 link, will terminate
management. These tests will be blocked and an Error Message displayed on the screen. Examples
of this are “BERT to Netw” and “Test Pkts to Netw” where the DLCI selection matches the
management DLCI of this unit.
