1. DESCRIPTION

This Engineering Technical

SERVICE ACCESS UNIT FOR DISA

Information (ET11 Bulletin describes the steps necessary to connect a Teltone

.M-106 Remote Service Access Unit to an Electra Mark11 system for providing Direct Inward Service Access

(DISA). When connected to a non-dedicated line, this adaptor can function as a special off-premises

extension of the Electra Mark11 providing complete access to single line station features. With the unit

turned off via a remote night transfer switch, calls directed to the adaptor terminate at the Mark11

attendant station. When connected to a dedicated line, the adaptor functions primarily as a security device,

limiting access to the single line station features to off-premise callers using a security code.
