RAN Broadcast

[jimc911]

We have a Meridian 81C with Symposium running a 50 position 9-1-1 PSAP in Oregon. Current RANS advising callers of delays are produced from an Interalia MMU which is currently providing up to 8 callers the same announcement. Subsequent delayed callers wait until the RAN is ready and then they receive the message from the beginning.

A new MIRAN 3 card has been installed with 7 RAN ports and a port for DID remote access. We have 18 wired 9-1-1 trunks, 12 wireless 9-1-1 trunks and 10 emergency ten digit POTS and several DID's which receive a RAN specific to 9-1-1 and a secondary RAN advising of delays. Ten non-emergency POTS with CO transfer have their own RAN as well as a secondary announcement for delays. We have a route so agents can transfer 9-1-1 callers so they will hear the non emergency number and then be disconnected automatically.
Our usual logged on agents ranges from 10-18. We use Plant/CML VESTA as our CTI.

It is not unusual for one major accident on I5 to generate 20 calls to 9-1-1 at the same time.

To summarize:
9-1-1 primary RAN0 could have up to 45 callers
9-1-1 secondary RAN1 "
Non emergency primary RAN2 could have up to 10 callers
Non emergency secondary RAN3 "
Information RAN4 could have 2-3 callers transferred to it at once.

Any advice on how many callers we should provide RAN to simultaneously? We're trying to determine how many licenses to purchase.

Many thanks..

Jim

the lic is your limit up to 32 per channel. you can use more then a single trunk for a recording. what i've done in the past during a major call flood is give the supervisor a information announcement service.. overflow calls (while in que) hit that, she would notify callers on an as needed basis that all units were in route to hwy 15 at mile marker 20 (etc).. the next ava dispatcher will take your call... that gave the supervisor a prescreen option.. under normal conditions that recording was skipped (calls over 2 minutes) if a recording was not recorded the default recording ref'ed all agents busy.. 911 switches have special requirements.. my site is a hosp and during a major out on 95 we can take 1000 calls in 15 minutes... add a school bus to the mix and it doubles.. this is the 1st choice for major trama in a capital city
