OPTIONS

S1-1 CTONE

■ ON Enables continuous periodic wake-up tones to the ISDN switch or LULT device.

Wake-up tones are repeated at 17-second intervals.

■ OFF Default and normal condition, in that the TRI-C sends one wake-up tone on power-up

only.

S1-2 TEST

■ ON Used for factory test only.

■ OFF Default and normal mode.

LOOPBACK TEST (ADR1 – ADR4, NT1)

Loopbacks in the network to customer direction can be initiated from either the ISDN switch (e.o.c.) or from the faceplate of the TRI-C. Loopbacks initiated from the faceplate are non-intrusive to the other B and D channels. To initiate a loopback, perform the following steps:

1. Connect the DS0 digital test set (e.g., TPI 108/109) to the 8-pin RJ-45 jack of the TRI-C and configure the set for Near Logic and 64 kb/s.

2. Rotate the 8-position rotary switch clockwise or counterclockwise for B1 or B2 selection respectively, to the desired address.

3. The TEST LED will illuminate if the loopback is successful and will not illuminate if the loopback fails.

4. Send and receive 2047 pseudo-random data to the established loopback and observe the DS0 digital test set bit error count.

5. It is not necessary to exit the test mode to select additional addresses or to change the B1/B2 channel (CW, CCW ).

6. To terminate the loopback, remove the 8-pin modular ring and return the rotary switch to the

unused position (between OFC TX and ADR4).

Note: The rotary switch is only intrusive if a DS0 test set is connected to the 8-pin modular interface of the TRI-C. If a test set is not connected, the rotary switch does not function. The 8-pin connector should be male with all 8 pins straight-through (no crossovers).

DEPLOYMENT GUIDELINES

■ All loops must be non loaded

■ Actual Measured Loss (AML) not to exceed 52 dB @ 20 kHz (135 Ω termination) or 61 dB @ 40 kHz.

■ Loop length not to exceed 50 kft.

■ Maximum single bridged tap not to exceed 2 kft.

■ Maximum total bridged tap not to exceed 6 kft.

■ Maximum DC resistance not to exceed 2000 Ω.

WIRING CONNECTIONS

TURNUP

1. Set dip switches on both units according to circuit design and local practices.

2. Install both TRI-C and TRI-R using standard procedures. a) TRI-C inserts in T400 shelf, or MFT bay with MFT adapter. b) TRI-R inserts in standard non powered T200 or T400 NCTE mounting for indoor

installations, or mounts to a wall for outdoor NID installations.

3. When inserted in an active housing the two units go through a synchronization and activation

process during which all LEDs undergo an on/off sequence. Refer to STATUS LEDs on reverse side for LED descriptions.

4. After synchronization, which may take up to 90 seconds, the following LED indication will show: a) ACT LED – ON b) All other LEDs will be OFF until network occurrences cause illumination.

5. If LEDs in step 4 are as noted, proceed with loopback and BERT testing per specifications.

6. If LEDs in step 4 are in any other configuration, refer to

Troubleshooting.

7. The TRISDN system will be qualified at the 20 kHz frequency.

TROUBLESHOOTING

No Power at the TRI-R

■ Ensure TRI-C is supplying voltage to power the TRI-R. Measure T-R voltage at the frame (Tip to

Ground = -7 to -9 Vdc, Tip to Ring = -127 to -133 Vdc, Ring to Ground = -134 to -142 Vdc).

■ Measure T-R voltage at the TRI-R.

■ If voltage not present at the TRI-R, check continuity of cable pair.

■ If voltage is present a faulty TRI-R is indicated.

■ The TRI-R does not place a measurable short between tip and ring. Cable resistance must be

taken towards a manually applied short.

Power, but no Synchronization on TRI I/F

■ Check cable for load coils.

■ Check for excessive bridged taps.

■ Verify other deployment guidelines adhered to.

Excessive Errors on Loop

■ Compare resistance of individual conductors. If these are different, high-resistance or

intermittent opens may be indicated.

■ Check for excessive bridged taps.

■ Verify other deployment guidelines adhered to.
