This interface module delivers 6 ports of Ear and Mouth (E&M) interfaces. The design emphasizes Smart-Grid and low-latency applications environments. Typical uses cases for this module are Teleprotection and Land Mobile Radio applications. The module supports E&M type I II III and V on 2 or 4 wire modes with selectable 600 or 900 ohm impedances. The physical connectivity on the interface module is using standards based RJ-45 connectors. The E&M signals and voice data can be transported using CESoPSN with and without Channel Attached Signaling (CAS) over MPLS.
