Overview of DS3 port parameters

The following parameters are associated with a DS3 port. You can edit most of them.

DS3 Port Access Identifier (Ds3Aid) - the address of the DS3 port you are modifying. The address reads from left to right as follows:

NodeID-ShelfID-SlotID-PortID

NodeID is a number between 1 and 255. This number specifies the address of the Calix C7 node in the network.

ShelfID is a number between 1 and 5. This number specifies the address of the Calix C7 shelf on the node.

SlotID is a number between 1 and 20. This number specifies the slot on the Calix C7 shelf where the plug-in card resides.

PortID is a number between 1 and 4 for a DS3-4p card and between 1 and 12 for a DS3-12p card. This number specifies the port on the DS3 plug-in card.

Interface type (Intf) - the type of interface the DS3 provides. When the equipment type is DS3/EC1-12s, the interface type must be CCHAN. When the equipment type is DS3-4p or DS3-12p, the interface type must be either NNI or UNI.

Alarm indication signal (AIS) - controls how an AIS is transmitted from this DS3 port.

Yes sets the port to continuously transmit AIS.
No set the port to normal operation where AIS is transmitted only when a loss is detected.

Alarm indication signal type (AIST) - specifies the type of AIS signal that will be transmitted, and the AIS signal mode expected on input, should a failure condition occur. Note: For the DS3-4p or DS3-12p plug-in card, the only value accepted is NAS (North American Standard).

Idle signal (Idle) - indicates the transmission or non-transmission of the Idle signal. For the DS3/EC1-12s (CCHAN) plug-card, Idle is transmitted only in the INGRESS direction and not the EGRESS direction. For the DS3-4p and DS3-12p plug-in card, IDLE is transmitted only in the EGRESS direction.

Format (Fmt) - specifies the DS3 signal format. When the interface is UNI or NNI, the format must be CBIT. When the interface is CCHAN, either CBIT or M23 is valid.

Line build out (LBO) - specifies the line build out setting. The value range is 1 to 450 feet.

Grade of service (GOS) - uniquely identifies one entry in the Grade of Service table that contains the performance parameters and their associated threshold values that you want applied to the DS3 port.

External interface (Ext) - indicates whether or not the DS3 port represents an external path through the network.

ATM mapping (ATM) - specifies how the ATM payload maps into the DS3 frame. Valid mapping variables are Direct or PLCP (Physical Layer Convergence Protocol) mapping. NOTE: This parameter is not applicable if the interface type is Clear Channel (CChan).

Protection domain (PDom) - a unique integer that associates FFPs into a coordinated protection domain.

Primary service state (PST) - indicates the service state that you want the DS3 port to transition to after you execute this command.
