Data Port Channel Allocation (appears for the individual channel method only). Designates the DS0 channel to allocate to
this port (N1–N31 for the Network E1 interface and D1–D31 for the DTE Drop/Insert interface).
Line 1 displays the 31 channels for the Network E1 interface or the DTE Drop/Insert interface. Line 2 displays what is
allocated to the DS0 channel indicated in Line 1. Possible values for Line 2 are:
Value
Meaning
–
This DS0 channel is not allocated. You can modify this value on this screen.
Prt
n
This DS0 channel is allocated to port
n, where n is a number from 1 to 4. You can modify this value
on this screen for this port only.
N
n
This DS0 channel is allocated to the Network E1 interface DS0 channel
n, where n is a number from 1
to 31. You cannot modify this value on this screen.
D
n
This DS0 channel is allocated to the DTE Drop/Insert interface DS0 channel
n, where n is a number
from 1 to 31. You can modify this value on this screen.
Select the channel by pressing the Function key under that number. To deallocate a port, press the Function key under
that port number. Pressing the Function key under channels assigned to other ports has no effect.
NOTE: The E1 DSU/CSU automatically derives the data rate for the port from the number of DS0 channels allocated.
NOTE: If time-slot 16 is reserved for signaling , D16 automatically connects to N16 and cannot be changed from this
screen.
NOTE: For the 3174 DSU/CSU there is a hardware limitation that limits the combined bandwidth used by Port1 and
Port3 to a total of 2048 kbps and the combined bandwidth used by Port2 and Port4 to 2048 kbps. If a selection
of Prt
n causes this limit to be exceeded, the selection is ignored and the “–” will continue to be displayed for the
channel.
