[comp.dcom.telecom] CCIS vs. Inband Signalling Question

phil@east.berkeley.edu (Phil Lapsley) (01/16/90)

Does anybody know what percentage of interoffice trunks now send
signalling information out of band via CCIS?  Before the breakup, Bell
Labs made some comment like it would be 100% CCIS by 1988, but I still
hear those MF tones in the background occasionally.
