Configuring the WAN Ports
XSR Getting Started Guide 3-9
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-crc4 for
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.
4. Enter encapsulation ppp to select PPP encoding.
5. Enter no shutdown to keep the BRI interface enabled.
BRI Leased Frame Relay
1. Enter interface bri 0:<1 | 2>.<1-30> to acquire BRI Interface mode and select the BRI
port and channel 1 or 2.
2. Enter encapsulation frame-relay to select Frame Relay encoding.
