Not sure it this is the right category for this question. I’m looking for some C.O. help. It has to do with 5ESS and E911. A tech I used to work with said they had failures on both 911 trunk groups (SS7) from a local 5ESS. The calls to 911 went to busy. I questioned him on this thinking that it was probably reorder but he was told busy. This tech is not a C.O. type. He maintains the 911 equipment and he very knowledgeable.
His question to me was he there any fail over that would route the 911 calls to a local POTS number in the event of a duplex failure. I know is the Optical Remotes there was a standalone feature that would route 911 calls to a POTS number if the ORM went into standalone but I don’t remember anything similar for the Host switch. That was 9 years ago. I didn’t know if any of the C.O. guys would have any ideas on this. I suggested assigned a route index to point to an announcement trunk that could direct callers to a local fire house number.
Any help that you can provide to this tech will be greatly appreciated.
