Fujitsu SRS-2100 manual Voice Features, Data Features

(Fujitsu SRS -2100

The basic ISDN service provides two 64,000 bits per second "B" channels for voice or data communications. Each B-channel can support circuit - switched or packet-switched data services. There is also one "D" channel, at 16,000 bits per second, for network signaling and packet- switched data service. The combination is often referred to as "2B+D", or the Basic Rate Interface (BRI).

Voice Features

The voice features of an ISDN telephone have several advantages:

∙They allow your telephone to handle multiple calls simultaneously, receiving calls while keeping others on hold.

∙They also permit a call coming in to a single directory number to ring more than one physical telephone. This feature facilitates call handling within a group.

∙They provide easy-to-use-accessto powerful features such as call conferencing and call transfer, to enhance your productivity.

∙They allow the incoming directory number to be dis played if it is available.

Data Features

The voice/data version of the SRS-2100 includes the following data capabilities:

∙Communication on the D-channel using packet switching with an asynchronous RS-232 terminal at terminal speeds up to 19,200 bits per second

∙Communication on the B-channel using circuit switching with an asynchronous RS-232C terminal at speeds up to 38,400 bits per second

∙Communications on the B-channel using circuit switching via an RS- 232 connector for synchronous data transmission at speeds of 56,000 or 64,000 bits per second.

The supporting network data features must also be assigned to the line.
