I have a cics with a caller id cartridge, which goes into slot 3. The ics#1 (station ports) will it be 101-116 and ata-117 and rad-118, which we don't use, then ics#2 c.o. lines 201-204 (001-004), which we are only using 3 c.o. lines. I"m going to use this configuration. I hope this is correct. Thanks
