TONE-BD (Tone-Clock Circuit)
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.
■ TONE-PT (Tone Generator)
■ TDM-CLK (TDM Bus Clock)
■ SYNC (Synchronization)
■ ETR-PT
■ PKT-INT (IPSI only)
