STATUS LEDs
LP
●
●
OFF
TRI loop sync has been established and no Near End Block Errors
(NEBE) are being received from the loop interface
●
RED
TRI-interface is out of sync or there is loss of signal
●
YELLOW
Indicates a BER of 10
-5
has been detected
✷
FLASHING
Flashes upon receipt of a Near End Block Error (NEBE) or when a
BER > 10
-6
is detected during Local Performance Monitoring
CR
●
●
OFF
Carrier sync (framing per TR-TSY-000397) has been established
and no Near End Block Errors are being received frrom the carrier
interface
●
RED
No framing pattern is being received
●
YELLOW
A BER > 10-5 has been detected
✷
FLASHING
Flashes upon receipt of a Near End Block Error (NEBE) or when a
BER > 10-6 is detected during Local Performance Monitoring
ACT
●
GREEN
Layer 1 from the ISDN switch to the customer ISDN terminal
equipment has been established
TEST
●
GREEN
Unit is in Local Performance Monitoring mode or the local test
pattern gen/det in invoked
●
YELLOW
Front panel test has been successssfully initiated or unit is
responding to a 2B+D loopback request
✷
FLASHING
Flashes once every two seconds when responding to a B1 loopback
request or when forced into a B1 loopback from the front panel.
Flashes twice every two seconds when responding to a B2 loopback
request or when forced into a B2 loopback from the front panel.
ERR
✷
FLASHING
Errors detected by local test pattern detector
FACEPLATE SWITCHES
Rotary Switch - used to select circuit elements for loopback testing
■
AD1 – selects address of local unit for loopback
■
AD2 – selects address of next unit downstream for loopback
■
AD3 – selects address of second unit downstream for loopback
■
AD4 – selects address of third unit downstream for loopback
■
AD5 – selects address of fourth unit downstream for loopback
■
AD6 – selects address of fifth unit downstream for loopback
■
LPBK – forces this unit to set up bidirectional loopback for selected B1 or B2 channel
■
CRTX – sets up loopback toward carrier
■
LPTX – sets up loopback toward the loop
■
NT1 – selects address of the NT1 for loopback
■
TEST – initiates selected loopback test from rotary switch
DIP SWITCHES
■
B1/B2 – selects which B channel, B1 or B2, to be tested during local tests
■
NORM/PTRN – used to select whether test pattern is sent from a test set or the unit itself
NORM – test pattern is sent from test set plugged into faceplate bantam jacks
PTRN – test pattern, 2047, is internally generated and transmitted

HANDLING PRECAUTIONS REQUIRED.
LOGIC BANTAM JACKS
■
Used to perform upstream and downstream testing with a DS0 level tester such
as a TPI 108/109 or Fireberd 4000/6000.
Rx (OUT) – transmits signal out to unit being tested
Tx (IN) – receives signal in from unit being tested

SW1-6: Zero Byte Substitution (ZBS)
■
Enables or disables ZBS
Note: ZBS must be set the same for the COT and RT. For AMI-provisioned carriers,
ZBS should be enabled. Setting is optional for B8ZS-provisioned carriers.
COMPLIANCE
This product is intended to be installed
in products providing a Type “B” or “E”
