UDS1-BD (UDS1 Interface Circuit Pack)
Echo cancellation on the TN464GP/TN2464BP is selectable per channel, even though it is
administrable on a per trunk-group basis. For example, if all but two ports on a TN464GP/
TN2464BP need to have echo cancellation applied, those two ports must be put in a trunk
group where the DS1 Echo Cancellation field is n. The remaining ports are in a trunk group(s)
where the DS1 Echo Cancellation field is y. A user can cancel echo coming from the network
(far-end echo) or coming from the switch (near-end echo).
The TN464 UDS1 Circuit Pack
The TN464C, D, E, F, and GP Universal DS1 Interface circuit packs provide an interface to the
DS1 facility, and are designed to support 24 DS0 channels on a 1.544-Mbps DS1 link, or 32
DS0 channels on a 2.048-Mbps link. The DS0 channels can be administered as trunks to other
switches, lines to off-premises stations, ports to line-side PRI terminating devices, or ports to
other line-side non-PRI terminating devices. (DS0 channels on TN464/Bs can only be
administered as trunks to other switches.) For more information about how TN464 ports can be
used, see the following MOs:

TN464GP provides Echo Cancellation, and in addition, the TN464GP
firmware may be updated using the firmware download feature.
Throughout this Maintenance Object (UDS1-BD), the term TN464 will mean any TN464C or
higher suffix UDS1 circuit pack. If part of this section refers to a specific suffix TN464 board, it
will be noted as such.
