This manual includes instructions for installing Jessica around the world, so it will contain references to both T1 and E1

signaling (digital telephone signaling protocol) installation procedures. In some places the notation 23/30 is used; the 23

indicates the number of T1 voice channels and the 30 indicates the number of E1 voice channels. The configuration and

installation of the MD110 are covered in the Ericsson documentation listed below (documents with the BC number). A

section on configuring the MD110 is provided in LBI-39039, and a sample configuration disk is also supplied. Jessica is not

a local interconnect system associated with EDACS single-site systems. For information on local interconnect, refer to the

subject LBI presented in the list that follows.

The manuals listed below are referenced throughout this document. Some provide additional background information

and others may be useful for solving technical difficulties.

1.1. MAJOR COMPONENTS

Jessica contains three major components: a PBX interface (PI), an MD110 PBX, and a multiplexer (MUX).

The PI provides the interface between the IMC and the MD110. It is responsible for telephone interconnect call

management. The PI has a VME bus architecture that includes three primary boards and the miscellaneous equipment below.

• PI Controller (PIC) Board -- a single-board computer that utilizes a CISC 32-bit microprocessor. The PIC is

responsible for processing all interconnect calls. It also controls the interfaces to the floppy and hard drives through

a small computer systems interface (SCSI) port.

• PI MSC Interface (PMI) Board -- a wide-area network (WAN) server board that provides a high-level data link

control (HDLC) link to the PIM controller board within the IMC.

• Primary Rate Interface (PRI) Board -- provides the E1/T1 ISDN interface to the MD110 as well as the E1/T1 audio

interface to the IMC. If a T1 link is specified, a PRI-48 is used. If an E1 link is specified, a PRI-64 is used.

• Hard Drive -- drive used for storing the application code, configuration parameters, and call activity.

• Floppy Drive -- a 1.44 Mbyte, 3-1/2" drive for configuration parameter updates and application code upgrades.

• VT100 field terminal -- used to manipulate files on the PI via a pSOS (UNIX-like shell) terminal interface running

on the PIC.
