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.
