Configuring line settings and signaling for T1

1.Select T1/E1 Link on the Configuration Menu. The T1/E1 Link Activity window appears (see figure 27 on page 42).

2.Link: 1 corresponds to Line 1 on the RAS. This is the primary link for dial-in callers. Under Link 1, Click on Configuration then Modify. The Line Interface Settings section of the WAN Circuit Configuration window appears (see figure 28 on page 42).

Configuring the line settings

1.Click on the Line Type pop-up menu (see figure 28 on page 42) and choose from the following options:

–dsx1ESF Extended SuperFrame DS1

–dsx1D4 AT&T D4 format DS1

–For ISDN PRI service, set the line type to dsx1ESF

2.Click on the Line Coding pop-up menu (see figure 28 on page 42). The most common options are: dsx1B8ZS and dsx1AMI. For ISDN PRI service, set the line coding to dsx1B8ZS.

3.Click on the Line Build Out pop-up menu (see figure 28 on page 42) and select t1pulse0dB(1).

4.Click on the Yellow Alarm Format pop-up menu and choose linkYellowFormatBit2(1).

5.Click on Submit Query.

At this point, the WAN front panel LEDs will become active. A solid green FRAME light indicator means that the RAS has synchronized with the T1 line.

If you have an T1/PRI (ISDN) line, refer to “Setting the line signaling for an ISDN/PRI line”. Otherwise, refer to “Setting the line signaling for a robbed-bit T1 line”.

Setting the line signaling for an ISDN/PRI line

Do the following:

1.Scroll down the WAN Circuit Configuration window, until the signaling Settings section appears (see figure 29 on page 43).

2.Click on the Signal Mode pop-up menu and choose messageOriented(4).

3.Click on the Message Oriented Switch Type pop-up menu (see figure 29 on page 43) and choose either ni1(National ISDN 1), dms(Nortel Switch) or att(AT&T Customer).

4.Click on Submit Query.

Signaling is now configured for ISDN/PRI.

Setting the line signaling for a robbed-bit T1 line

Do the following:

1.Scroll down the WAN Circuit Configuration window, until the signaling Settings section appears (see figure 29 on page 43).

2.Click on the Signal Mode pop-up menu and choose robbedBit(3).

3.Click on Submit Query.
