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

SUBJECT TO ELECTROSTATIC DAMAGE

OR DECREASE IN RELIABILITY.

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”
enclosure and in restricted access location
only.
