This rugged, environmentally hardened multiplexer allows you to send multiple voice and data streams over 14 internal channels. The comprehensive selection of interfaces allows you to design a multiplexer which meets your particular requirements. The OM-12 rear module holds the main interface card.
A second option module may be added which allows a telephone connection at one OM12, and a CO/ PBX connection at the other OM12. Alarm contacts on the back of the OM12 indicate a power-supply or an optical link failure.
