EQP Speed

Type the transmission speed for each port on the next line of the menu.

This rate must be 56 kbps, 64 kbps, or a multiple of either rate. The total

(aggregate) rate for the data ports of all DIU 2130s and DIU 1130s

connected to a CSU cannot exceed 1.536 Mbps. This parameter is

informational only.

64K Mode

If you set this option to YES, each channel of the DS1 line carries 64 kbps

of data. If you set this option to NO (default setting), each DS0 channel

carries 56 kbps of data. If the data rate of your equipment is a multiple of

56 kbps, set this option to NO. If it is a multiple of 64 kbps, set this option

to YES.

Loop

If you enable this option (Y), the DIU responds to loopback commands.

Scramble

The customer data on a DIU data port may require protection from

unauthorized access.

If scrambling

is required, set this option to YES on each equipment (EQP)

port. This setting allows the DIU to randomize the data before

multiplexing and sending it to the CSU.

If scrambling

is not required, set this option to NO (default setting) on the

associated DIU data port.

Be sure to set the Scramble option the same way at the far-end NCC,

DIU 1130 so that it can restore the original customer data upon receiving

it.

EQP Clock

Select the timing source for the incoming data from the customer data

equipment. This can be either the TT (Transmit Timing) signal from the

data equipment or an internal clock (either ST or inverted ST) generated

by the DIU. If the TT lead is not available from the data equipment,

select either ST or INVERT ST to have the DIU clock the data in. The

ST choice depends on which clock signal transition is to be used for data
