Yes, I used backup interface dialer command as follows.
When the T1 serial0 interface on rtr A goes down, and the dialer dials rtr
B, the call
got rejected with debug info showing "the dialer on rtr B is already in
standby mode
and can not take incoming call".

rtrA se0<----------------->se0 rtrB
    bri0 <- - backup - -> bri0
   dialer1 dialer2

rtrA:

hostname A

isdn switch-type basic-ni

interface se0
  clockrate 64000
  ip addr 10.1.1.1 255.255.255.0
  backup interface dialer0
  backup delay 2 5
  backup load 70 10

interface bri0
  isdn spid1 555101 5551
  isdn spid2 555201 5552
  encap ppp
  dialer pool-mem 1

interface dialer1
  ip addr 10.1.2.1 255.255.255.0
  encap ppp
  dialer pool 1
  dialer string 6661
  dialer remote-name B
  dialer-group 1

dialer-list 1 protocol ip permit
dialer-list 1 protocol rip permit <-- is this permit clause redundant ??

router rip
  network 10.0.0.0

rtrB:

hostname B

isdn switch-type basic-ni

interface se0
  ip addr 10.1.1.2 255.255.255.0
  backup interface dialer2
  backup delay 2 5
  backup load 70 10

interface bri0
  isdn spid1 666101 6661
  isdn spid2 666201 6662
  encap ppp
  dialer pool-mem 2

interface dialer2
  ip addr 10.1.2.2 255.255.255.0
  encap ppp
  dialer pool 2
  dialer string 5551
  dialer remote-name A
  dialer-group 2

dialer-list 2 protocol ip permit
dialer-list 2 protocol rip permit

router rip
  network 10.0.0.0

When I tried to put in another dialer3, it complains that "the dialer
remote-name A is already used in dialer 2"

Thank You!

Do you use "backup interface" command on both side?

paste your config, maybe that can help us understand your problem.

Router A and router B need to use dialer profile to backup a T1 link
between them.
When the T1 serial0 interface on rtr A goes down, and the dialer dials rtr
B, the call
got rejected with debug info showing "the dialer on rtr B is already in
standby mode
and can not take incoming call". Well, how would you configure the dialer
on rtr B
for it to take incoming calls from rtr A, if I do want the dialer on rtr B
to be a mutual
backup interface, which will put it into standby mode?
I've tried to create another dialer interface on rtr B, but when I typed in
dialer remote-
name rtrA, it complains that rtrA is already specified with the first
dialer on rtrB.
What do I need to do in order to setup this mutual dialer backup b/w rtrA
and rtrB?

Thank You!
