Description
The ESIB(8)-U20 ETU is the basic Electronic Station Interface ETU
that provides an 8-channel interface for Multiline Terminals,
Attendant Consoles, and Single Line Telephone SLTII(1)-U( ) ADPs.
This ETU also provides one circuit (B1 channel) support for devices
such as the PGD(2)-U10 ADP (adapter) that can be used to connect
Door Boxes, External Speakers with Amplifiers, External Music
Sources, External Recording Systems, and External Ringing. This
ETU can be expanded to 16 channels by installing the ESIE(8)-U20
ETU. When an ESIE(8)-U20 is installed on the ESIB(8)-U20, the
combination can support two circuits (B1 and B2 channels) for
AP(R)-R units or the PGD(2)-U10 ADP.
