L2 PROTOCOL (T1 ATM FIRMWARE) – DSX INTERFACE

Configure the L2 PROTOCOL parameters and view the status of the integrated DSX interface using items

from this menu.

L2 PROTOCOL (T1 ATM – DSX) > CONFIG

Configures the voice parameters for the interface.

INTERFACES (T1 ATM – DSX) > CONFIG > SIGNALING

Configures the voice signaling implemented on the interface. The signaling must match the network

application. The choices are:

INTERFACES (T1 ATM – DSX) > CONFIG > TX OAM

Configures the Total Access 850 to transmit an Operation, Administration, and Maintenance (OAM) cell

to the network (voice gateway) when the DSX interface is down.

INTERFACES (T1 ATM – DSX) > CONFIG > RX OAM

Configures the Total Access 850 to transmit an alarm condition to the DSX interface when the network

(voice gateway) is down.

INTERFACES (T1 ATM – DSX) > CONFIG > LEGACY CONFIG

Digital trunk channel ID's are bits used to identify voice calls being carried within ATM cells. Some

gateways do not support higher channel IDs, therefore the Total Access 850 supports CIDs from 16 or 65.

The default is

DSX CID FROM 65.

CR COUNT Number of packets received on an individual DLCI with the CR bit set

BECN C

OUNT Number of packets received on an individual DLCI with the BECN bit

set

FECN C

OUNT Number of packets received on an individual DLCI with the FECN bit

set

NKNOWN FRAME RX Frames received that were not associated with any PVC entries

E&M (T

ANDEM) Sets the DSX interface to use E&M signaling.

OOP START Sets the DSX interface to use loop start signaling.

ROUND START Sets the DSX interface to use ground start signaling.

ISDN PRI Sets the DSX interface to use common channel signaling for ISDN.
