Configuring the WAN Ports

This command allows multiple logical WAN interfaces to be created on a single channelized T1/E1/ISDN-PRI port, ranging from 0 - 23 for T1 lines, and 0 - 31 for E1 lines. Also, from 1 - 24 T1 and 1 - 31 E1 timeslots can be set. Channel speed options are 56 (T1) or 64 (E1) kbps.

Note: Channel group and timeslot number ranges are different. Be sure to match them correctly and within the range. Also, when adding a second T1 or E1, be sure to begin channel numbering again at 0.

6.Enter framing <sf esf crc4 no-crc4> to set the framing type.

The value you set must match the type and format offered by your service provider and must correlate with the NIM card you are configuring: sf or esf for T1 cards, and crc4 or no-crc4for E1 cards.

7.Enter linecode <ami b8zs hdb3> to configure the encoding type.

This setting must match your service provider’s linecode type and type of NIM card installed: B8ZS for T1 only, HDB3 for E1 only, and AMI for both T1/E1.

8.Enter interface serial <slot # card # port #> of the serial NIM card to acquire Interface mode and configure the logical interface.

9.Enter encapsulation ppp to set the encapsulation type.

10.Enter ppp authentication <chap [ms-chap] [pap] pap [ms-chap] [chap] ms-chap [chap] [pap]> for the authentication type on the port.

11.Enter ip address <xxx.xxx.xxx.xxx> <yyy.yyy.yyy.yyy> where x is the IP address and y is the subnet mask of the serial port.

12.Enter backup interface dialer <number> to allow the serial interface to set the specified dialer interface as a dialed backup.

13.Enter no shutdown to keep the interface enabled.

14.Enter show controller <T1 E1> <slot/card/port> to verify NIM settings.

15.Enter show interface serial <slot# card#: channel#> to verify serial port settings.

16.Enter show ppp interface serial <card#port#:channel#> to display PPP status on the interface.

17.Enter show dialer to verify your dialer interface configuration. Remember to save your configuration after all edits.

BRI Configuration

ISDN BRI can be configured on a leased (over PPP or Frame Relay) or non-leased, switched line. Continue configuration with the BRI type of your choice.

BRI Leased Line

1.Enter interface bri 0:<1 2> to acquire Interface mode and select the BRI port and channel 1 or 2.

2.Enter leased-line <64 128> to acquired BRI interface mode and select 64 or 128 kbps line speed. Selecting 128 assigns B1 and B2 timeslots to channel 1 while 64 assigns either B1 or B2 timeslots to channel 1 or 2.

3.Enter ip address <xxx.xxx.xxx.xxx>/24 to set an IP address for the BRI interface.
