Data Port Rate (appears when using the block or ACAMI channel allocation method, or when a synchronous data port is

assigned to another synchronous data port). Designates the data rate for the port. Available selections depend on the

current base rate configured for the port. The factory default for Nx64 is 384 kbps, and Nx56 is 336 kbps.

NOTE: This configuration option does not appear if the individual channel allocation method (Chan) is selected using the

Assign By configuration option.

NOTE: Changing this configuration option from one rate to another deallocates all DS0 channels assigned to either the

network interface or the DTE Drop/Insert (DSX-1) interface.

NOTE: When you enable EDL (for 2-port and 4-port DSU/CSUs), 8 kbps of the total bandwidth allocated for this port is

not available to the synchronous data port. For example, if you select 256 kbps and EDL is enabled, only

248 kbps are available.

NOTE: When you enable EDL (for 2-port and 4-port DSU/CSUs) on a synchronous data port and the clock source is set

to that synchronous data port, the external device must provide a clock of 8 kbps less than the expected data

port rate. For example, if you select 64 kbps, the external clock source must supply a 56 kbps clock signal.

NOTE: For the 3164 DSU/CSU there is a hardware limitation that limits the combined bandwidth used by Port 1 and

Port 3 to a total of 2048 kbps and the combined bandwidth used by Port 2 and Port 4 to 2048 kbps. Thus, when

entering this menu, the rate choices are limited due to this constraint. This limitation only occurs in configurations

mapping a port to a port or when mapping ports to the DTE Drop/Insert (DSX-1) interface and to the network.

Data Port Channel Allocation (appears for the block and ACAMI methods only). Designates the starting DS0 channel,

N1–N24 for the network interface and D1–D24 for the DTE Drop/Insert (DSX-1) interface.

Available selections are only those DS0 channels that provide enough bandwidth (based on the configured data rate) to

be used as a starting channel number.

Select the desired starting channel number by pressing the Function key under that number. When you make the

selection, the DSU/CSU allocates the correct amount of DS0 channels to support the data rate currently configured for

the port.

Clear – Deallocates all DS0 channels for this port from the network interface or the DTE Drop/Insert (DSX-1) interface.

NOTE: This configuration option is not available if the individual channel allocation method (Chan) is selected using the

Assign By configuration option, or if Prt

is selected using the Assign To configuration option.
