4. If the error has not been corrected at this point, there is a problem with the TDM bus 
within the port network containing the reported Tone-Clock circuit. This may include TDM 
bus intercarrier cables, bus terminators, bent pins on the backplane, and errors on any 
circuit pack plugged into the same port network. See 
m. Error Type 2561: a Tone-Clock circuit pack, with a different circuit-pack code as required for 
this system, has been inserted in the port slot as shown in the Hardware Error Log. To 
resolve this error, se
appropriate circuit pack code and replace the Tone-Clock circuit pack according to the 
procedures indicated for this system. The meanings of the Aux Data values are as follows:
n. Error Type 3329: the system attempted but failed to interchange IPSI or Tone-Clock circuit 
packs. (This error occurs only in port networks with duplicated Tone-Clocks.) The fault may 
lie in the standby Tone-Clock or in the circuit pack that controls selection of the active 
Tone-Clock (the t/c selector). The goal of the following procedure is to ensure that both 
Tone-Clocks can be interchanged to while either t/c-selector circuit pack is active.
1. Examine the Error Log for errors reported against circuit packs in the same port network, 
paying special attention to TDM-CLK, TONE-BD, DUPINT, SW-CTL, and EXP-INTF. 
Follow the procedures indicated for any such errors found. After eliminating the above 
potential problem sources, proceed with the following steps.
2. Determine which circuit pack was controlling the choice of Tone-Clock at the time the 
error occurred.
The t/c-selector circuit pack of interest is the one which was active at the time the error 
was logged. An EXP-LNK interchange since the time of the error may have made that 
circuit pack the current standby. Determine whether an interchange affecting the t/c 
selector has occurred since the TONE-BD error. Look for EXP-LNK entries in the 
hardware error log for PNC interchanges, which would affect the EXP-INTF.
3. If the t/c selector has not undergone an interchange since the error occurred, go to the 
next step. If such an interchange has taken place, interchange back to the formerly active 
t/c selector. Use set expansion-interface. If the interchange attempt fails due to 
other errors, resolve those problems first.

A TN756 Tone-Clock circuit pack (instead of a TN2312) is in a standard- or 
duplex-reliability system’s PN.
1003
Either a TN741, TN714, TN768, TN780, or TN2182 Tone-Clock circuit pack 
(instead of a TN2312 IPSI) is in a standard- or duplex-reliability system’s 
PN.
1004
Either a TN741 or TN714 Tone-Clock circuit pack (instead of a TN768, 
TN780, TN2182, or TN2312) is in a high- or critical-reliability system’s PN.
