Data Port Channel Configuration Options

Channel Config:
Dsply Clear Prt1
NOTE: The configuration options described in this table are made available by selecting Prt1 from the Channel
Config screen.
Data Port Channel. Allows the assignment of a particular port to DS0 channels on the network interface.

Data Port Channel Allocation Method. If NET or DTE is selected using the Assign To configuration option, this
configuration option designates the method for assigning DS0 channels to the destination T1 interface.
Block – Allocates DS0 channels to this port by the block method.
ACAMI – Allocates DS0 channels to this port by the Alternate Channel Alternate Mark Inversion method. The difference
between block and ACAMI is that the number of channels allocated with ACAMI is double the number needed for the port
rate. With ACAMI, every alternate DS0 channel does not carry data from the port but always transmits and receives all
ones.
Chan – Allocates DS0 channels to this port by the individual channel method.
NOTE: Changing this configuration option from one method to another (Block, ACAMI, or Chan) deallocates all DS0
channels assigned to the network interface.
Port Rate: 384

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.
NOTES:This configuration option does not appear if the individual channel allocation method (Chan) is selected using the
Assign By configuration option.
Changing this configuration option from one rate to another deallocates all DS0 channels assigned to the
network interface.
