Table A-3. Cross Connect Assignments

Assign By
Available Settings: Block, ACAMI, Channel
Default Setting: Block
Specifies the method for assigning the synchronous data port’s DS0 channels to the
network interface.
Block – Allocates DS0 channels by the block method.
ACAMI – Allocates DS0 channels 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.
Channel – Allocates DS0 channels by the individual channel method.
NOTE: Changing this configuration option from one method to another (Block,
ACAMI, or Channel) deallocates all DS0 channels assigned to the network
interface.
Synchronous Data Port Assignments
Available Settings:N01, N02, ..., N24
P(
x
), P(
x
), ..., P(
x
)
Default Setting: P(B) (all DS0’s assigned to data port)
Designates the assignment of DS0 channels connected to the synchronous data port.
There are three rows in the assignment table. In each row, the top line displays
channels (DS0’s) for the network interface. The bottom line displays what whether that
DS0 is available (unassigned) or connected to the synchronous data port. If connected
to the synchronous data port, the value of P(
x
) specifies the assignment method used
for the connection:
Value Meaning
P(A) This DS0 channel is allocated to the synchronous data port using
the ACAMI method.
P(B) This DS0 channel is allocated to the synchronous data port using
the Block method.
P(C) This DS0 channel is allocated to the synchronous data port using
Channel method.
