Configuring DSL Connections (DSLTNT)

Configuring nailed connections

Set the Dial # parameter in the Configure profile to the DSL port number, which in the case of a single DSLPipe is always 1.

To configure a switched connection on the DSLTNT for an incoming connection from a DSLPipe, you must set the Call-Type parameter to Off in the Connection profile for the DSLPipe. For example:

admin> read connection dslpipe-1

CONNECTION/dslpipe-1 read

admin> set telco call-type = off

admin> write

CONNECTION/dslpipe-1 read

Configuring nailed connections

In a nailed connection, the DSLTNT and the remote unit always assume that the connection is up and do not attempt to verify that the line is operational.

A nailed connection does not record accounting or authentication information after the session is established and therefore cannot be used to bill for DSL service as if it were a call on an ISDN network or the PSTN.

Nailed connections are typically used for Frame Relay connections, but PPP can also be used. Voice calls are not supported over a nailed connection.

You specify whether an ADSL or SDSL connection is nailed by doing the following:

Specifying a nailed group number in the ADSL or SDSL profile

Setting Call-Type to FT1 in the Connection profile for the nailed connection

You specify whether an IDSL connection is nailed by doing the followings:

Specifying a nailed group number in the IDSL profile

Setting Channel-Usage to Nailed-64-Channel in the IDSL profile

Setting Call-Type to FT1 in the Connection profile for the nailed connection

You configure the DSLPipe for a nailed connection in a similar way to other Pipeline nailed connections:

In the Configure profile, set Chan Usage to Leased/Unused.

In the Connection profile for the DSLTNT, set Call Type to Nailed in the Telco Options submenu.

In the Connection profile for the DSLTNT, specify a Group number in the Telco Options submenu.
