TONE-BD (Tone-Clock Circuit)

MO's Name (in

UU is the universal cabinet number (1–44 for CSS PNC, 1–64 for ATM PNC). C is the carrier designation (A,

B, C, D, or E).

The TONE-BD MO supports EPNs in an S8700 Media Server system using either

a TN2312 IP Server Interface (IPSI) circuit pack, or for non-IPSI EPNs equipped

with Tone Clock circuit packs.

For IPSI-equipped EPNs, the TONE-BD MO consists of a module located on the

IPSI circuit pack and provides tone generation, tone detection, call classification,

clock generation, and synchronization. (It replaces the TN2182B Tone-Clock

board and is inserted into each EPN's Tone-Clock slot.) For non-IPSI EPNs, the

TN2182B Tone-Clock circuit pack provide the previous functions.

The TN2312 IPSI circuit pack (for an EPN equipped with IPSIs) or the Tone-Clock

circuit pack (for a non-IPSI EPN) both contain two independent components:

Tone Generator that provides every tone needed by the system

Clock that generates the system clocks for both the Time Division Multiplex

(TDM) bus and the packet (LAN) bus

It also aids in monitoring and selecting internal synchronization references.

When resolving an IPSI or Tone-Clock circuit pack's errors/alarms, the following

sections should also be consulted:

For non-IPSI EPNs, use the set tone-clock UC command to establish the

tone and synchronization resources for the system.

For IPSI EPNs, use the set ipserver-interface command to establish the

tone and synchronization resources for the system.
