Chapter 3. Operation

CONFIG

Read Security: 5; Write Security: 5

Contains parameters to include T1 data streams to the HSSI interface.

PRT

Displays the port number for the T1s mapped to the NxT1 HSSI interface. Ports 1 through 4 are the T1 interfaces located on the NxT1 HSSI Option Module. Ports 5 through 8 are T1s mapped to the NxT1 HSSI Option Module in the Dedicated Maps.

GROUP ASSOCIATION

Associates T1s (either mapped to this card and/or the on-board T1s) with the HSSI interface data stream. To add the T1 to the data stream, select the GROUP1 option.

SCRAMBLE

Enabling the SCRAMBLE option configures the NxT1 HSSI Module to prevent ones density violations when transmitting ADTRAN IMUX headers on a T1 circuit with AMI line coding.

Use extreme caution when disabling the SCRAMBLE option. ADTRAN recommends enabling the SCRAMBLE option for normal use.

HSSI MENUS	Read Security: 5
	Provides status, configuration, and testing parameters for the 50-pin SCSI-
	II HSSI interface.
	STATUS
	Read Security: 5
	Displays the current loopback status of the HSSI interface
	LOOPBACK
	Displays the current loopback status of the HSSI interface. The fol-
	lowing loopback options are possible (see Figure 3-4 on page 37):
	LOCAL DTE LOOPBACK
	A local DTE loopback occurs at the DTE port of the DCE, and is
	used to test the link between the DTE and DCE (NxT1HSSI mod-
	ule).
	LOCAL LINE LOOPBACK
	A local line loopback occurs in the IMUX engine and is used to test
	functionality between the DTE and the IMUX engine.
	REMOTE LINE LOOPBACK
	A remote line loopback occurs at the T1 interface and is used to test
	functionality between the DTE and the T1 interfaces.
