S8700 series
The following circuit-pack code(s) are supported:
S8700-series

TN768
S8700-series
Fiber-PNC:
TN780
S8700-series

TN2182
This is a general-purpose Tone-Clock circuit pack for EPNs. It can be used in
every situation, except as the Master Tone-Clock circuit pack when a
Stratum-3 clock is administered.
The Stratum-3 clock feature requires the use of this circuit pack code in PN 1.
The Stratum-3 clock will operate only with this code as the Master Tone-Clock
circuit pack. The TN780 circuit pack is upward compatible with the TN768
code, and can be used in any place a TN768 would be allowed. The TN780 is
used in many countries outside the U.S. where the TN768 does not provide
local tones.
This Tone-Clock-Detector may be used anywhere a TN768 or TN780 is used,
with the exception of configurations requiring Stratum-3 clock. The TN2182
may be used in all country configurations.
TN2312 The TN2312 IPSI circuit pack supplies Tone-Clock functionality for S8700
systems.
Port Networks with a Single Tone-Clock Circuit Pack
This procedure is destructive.
1. Pull out the defective IPSI or Tone-Clock circuit pack. This will remove the clocks and
cause the system to activate emergency measures. If this is an IPSI supported port
network, use busyout ipserver-interface:
● All calls to and from the PN will drop, and the PN will activate Emergency Transfer
within about one minute. But the rest of the system should operate normally.
2. Insert a new IPSI or Tone-Clock circuit pack. The system will detect the return of the clocks
and will automatically recover as follows:
● The system will reset the PN (PN cold restart), and all of the PN’s red LEDs will come
on and go off within 30 seconds.
3. If the red LEDs come on but do not go off within 30 seconds, pull the circuit pack out and
reseat it. If the LEDs perform as expected this time, continue with step 6. Otherwise, there
may be a problem with the TDM bus; possibly a bent pin in the IPSI or Tone-Clock circuit
pack’s slot. Follow the directions in the TDM-BUS maintenance section.
4. If the red LEDs did light, as explained above, then go to Step 6. If the red LEDs do NOT
light, as explained above, then go on to Step 5.
