Just confirming: We have the exact same problem! We are trying to replace our Ascend routers with Cisco 2621 routers. We were able moved our 2621 on the receiving end to another site/building with a different ISDN circuit to test it there. It worked just fine, both channels picked up, at the test site and worked they way we expected. We are now trying to convince a reluctant telco to dig further into the problem at our original site.
Even though our telco claims that the line is provisioned for rollover, we were never able to successfully bring up the second channel using only one dialer string; debug would always show the line busy. When using two dialer strings, router would call the second string before the switch was apparently able to handle it. We saw this indication when we added a third dialer string and it worked consistently on the third call. The Cisco tech recommended we configure router with "isdn fast-rollover-delay 5". With this command in the dialer interface and using only the two original dialer strings, both channels came up as expected.
Question We run asr9001 with XR 6.1.3, and we have a very long delay to
login w/ SSH 1 or 2 to the device compare to IOS device. After
investigation, the there is 1s delay between the client KEXDH_INIT and
the server (XR) KEXDH_REPLY. After debug ssh serv...
Introduction The purpose of this document is to demonstrate the Open

present in a non-backbone area. The V-bit is signaled in Type-1 LSA only
if the router is the endpoint of one or ...
