The TONE-BD MO supports PNs in a 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 PN’s
Tone-Clock slot. For non IPSI EPNs, the TN2182B Tone-Clock circuit pack provide the previous
functions.
The TN2312 IPSI circuit pack, for a PN equipped with IPSIs, or the Tone-Clock circuit pack, for
a non IPSI PN, both contains 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 location command to establish the
tone and synchronization resources for the system.
● For IPSI EPNs, use set ipserver-interface 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)
