Allocating Data Ports

You have the capability of assigning a specific port

(Prt1...Prt2 for Models 3160/3161, Prt1...Prt4 for
Model 3164) to DS0 channels on either the Network
interface or the DSX-1 Drop/Insert T1 interface using the
configuration options. Three methods are available to
assign DS0 channels to the port:

Block – Allows a block of contiguous channels to be

assigned by specifying a data port rate and a starting DS0
channel. The number of channels assigned is determined
by the port rate. Only those DS0 channel numbers that
provide enough bandwidth (based on the port’s data rate)
to be used as a starting channel number are displayed on
the screen. These channels are automatically assigned to
the destination T1 interface when the block method is
used and the starting channel is selected.

ACAMI – Allows a block of contiguous channels to be

assigned by specifying a data port rate and a starting DS0
channel. However, with ACAMI, the number of channels
assigned is twice the number needed for the port rate. This
is because with ACAMI, every alternate DS0 channel
(starting with the n+1 DS0 channel), does not carry data
from the port, but instead always transmits and receives
all ones.

Chan – Individually selects the DS0 channels to

allocate to the data port. The data port rate is
automatically determined based on the number of
channels selected.

Once a port is selected, you have access to

configuration options to complete the port allocation
procedure. These configuration options enable you to,

Assign the selected port to the desired interface

Select the desired method for channel allocation

Select the port rate and starting channel (if the
allocation method is block or ACAMI)

NOTE

For the 3164 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. Thus, the rate
choices shall be limited
appropriately due to this
constraint. This limitation should
only occur in configurations
mapping a port to a port or when
mapping ports to the DSX-1 and
to the network.

Select the specific channels if the allocation method
is individual channel

These configuration options are explained in detail in

Appendix C.
