Of the available IS II applications, you can connect only CAS IS II and SPM IS II
applications to a system that operates in Behind Switch mode.
Considerations and Constraints
9
IS II uses UNIX System V Release 3.2.2.
IS II stores up to 12 hours of voice-mail messages when IS II includes AVP and
over 200,000 call accounting records when IS II includes CAS.
You can install either IVP AA or AVP on the system, but not both.
The system supports up to 12 IVP AA ports (on three circuit boards).
If IS II includes AVP, when users receive voice-mail messages, the Message
LEDs on their telephones light if a mailbox has been assigned to each of those
telephones.
For AVP or IVP AA, the following symptoms indicate that the system needs more
TTRs:
■
Single-line telephone users do not get dial tone when trying to dial out.
■
AVP or IVP AA fails to transfer calls.
■
Calls either fail to ring or go to coverage prematurely.
You can print SPM IS II reports or save them on disk (floppy or hard disk). At the
same time, the report is displayed on the screen together with prompts for
browsing.
You should not print SPM IS II reports when the system is handling more than 100
calls per hour.
