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 32-channel interface is not supported on G3r V1
systems.) 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
