im trying to get an atm ds3 from bellsouth turned up on a cisco 7206 with
a pa-t3 card and not having much luck. ive searched through the list
archives and tried pieces of configs from different folks but no go.
my subscriber has a link and the bellsouth tech's can see the modem
my interface on my router shows up/up but all i see is input and no output
and most of the input is errors.
the router is connected to a ds3 that is fed off a lucent metropolis dmx
oc12 shelf. the atm switch is a lucent cbx. if i loop up my interface,
the lucent cbx can see the loop and a loop on the oc12 will show up on the
cbx.
bell is telling me im missing something in my config but wont/cant tell me
what and im at a loss. could anyone suggest anything?
my atm config is
interface ATM4/0
description DS3_ATM
no ip address
ip route-cache flow
no ip mroute-cache
atm clock INTERNAL
atm scrambling cell-payload
atm framing cbitplcp
atm uni-version 4.0
no atm auto-configuration
no atm ilmi-keepalive
no atm address-registration
no atm ilmi-enable
ive tried different framing (cbitadm, m23plcp & m23adm), different
uni-version, no scrambling, scrambling, clock internal and clock line - no
go on any of them.
Interface ATM4/0:
AAL enabled: AAL5 , Maximum VCs: 4095, Current VCCs: 5
Maximum Transmit Channels: 0
Max. Datagram Size: 4528
PLIM Type: DS3 - 45000Kbps, Framing is C-bit PLCP,
DS3 lbo: short, TX clocking: INTERNAL
Cell-payload scrambling: ON
33 input, 0 output, 0 IN fast, 0 OUT fast, 0 out drop
Avail bw = 45000
Config. is ACTIVE
ATM4/0 is up, line protocol is up
Hardware is ENHANCED ATM PA
