Description |
---|
When dialing is performed from the CODEC, an EIA-366 connection is made between the CODEC and the IMUX to carry the dialing instructions to the IMUX which actually performs the dialing function. This is not an issue if there is no EIA-366-A connection between the CODEC and the IMUX and all dialing is performed from the IMUX. |

Review the documentation to determine whether an approved EIA-366-A dial isolator is in place. DISN Video Services (DVS) maintains a list of A/B switches and dial isolators that have been TEMPEST certified to meet the above requirements at http://disa.mil/Services/Network-Services/Video/~/media/Files/DISA/Services/DVS/red_black_peripherals.xls. If a dial isolator is not implemented and used, or the dial isolator is not on the list, this is a finding. If there is no EIA-366-A connection between the CODEC and the IMUX and all dialing is performed from the IMUX, this is not a finding. |
