The display communication-interface command displays three different forms
depending on the object specified by the user. See also status link for more
details.
The hop-channels object displays translation data for hop channels. A hop
channel is a bi-directional network channel between two interface links for DCS
message hopping. A hop channel is used to tandem DCS messages from one
interface link to another interface link.
The processor-channels object displays translation information for each of the
local processor channels. A processor channel is one several data streams
which are multiplexed by the X.25 protocol onto a single data link. The system
has 128 total processor channels; up to 64 can be assigned to a single link.
The links object displays translation information for each communication
interface link. A link is an electronic communication channel transmitted over the
Packet Bus for carrying packet-switched data. There are 16 links which terminate
at one end on the Packet Interface circuit pack in the SPE. At the physical and
link layers, the link terminates at the other end on a port on the PBX’s switching
matrix. At a higher level, the link continues over a transmission facility to another
endpoint, such as a DCS node or AUDIX. The link carries application messages
between the SPE and other switches or adjuncts.
