i have two AS5200 (using them as routers) hooked up to a channelized T1 each. i’m trying to set up a ~1.5mbps link between them.
what happens is, i have the link up (all 23 channels in a bundle). there are no errors (dropped packets, etc) on interface se0:23 or dialer1. there are a few “line code violations” on SOME (not all) channels (as seen when doing show controller t1 0)
my problem is mostly that i can’t get any kind of decent performance (200-400 kbits instead of ~1.5Mbis)
in case it would help here’s the config i use (similar on both routers):
controller T1 0
framing esf
clock source line primary
linecode b8zs
pri-group timeslots 1-24
!
interface Serial0:23
no ip address
encapsulation ppp
dialer rotary-group 1
isdn switch-type primary-5ess
no fair-queue
no cdp enable
ppp multilink
!
interface Dialer1
ip unnumbered Ethernet0
encapsulation ppp
no ip mroute-cache
dialer in-band
dialer idle-timeout 0
dialer fast-idle 15000
dialermap ip 1.2.3.4 name cisco5-7 broadcast ##########
dialer load-threshold 1 either
dialer-group 1
no peer default ip address
no fair-queue
no cdp enable
ppp multilink
ppp multilink interleave
!
dialer-list 1 protocol ip permit
1.2.3.4 is the ip of the remote router
########## is the phone number
