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.
