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.
