The UPA 100 áU Protocol Analyzer monitors the 2B+D basic rate interface between the subscriber's equipment and the ISDN network. áBasic rate ISDN consists of two 64 KBPS á"B" channels and a single 16 KBPS á"D" channel. Signaling (off-hook), dial tone, dialing, etc.) takes place on the "D" channel in the form of packet messages. Circuit-Switched and packet-switched message decodes are supported.

The UPA "looks" at the messages being passed in both directions between the subscriber's equipment and the network, decodes them into plain English, displays them on the screen and places them in a capture buffer for later analysis. Options are provided for filtering out particular packet messages.

The UPA 100 supports layers 1, 2, and 3 and provides decodes to the screen of the host computer.

The UPA 100 is inserted between the Central Office ISDN Network and the customer premises equipment (CPE). áThe CPE may be an NT1 or a device with a built-in U interface. The UPA is transparent (non-intrusive) and may be used at the CPE or at the Central Office. The UPA connects directly to the "U" interface and therefore does not require an NT1 "front end". áTwo built-in "U" interfaces in a repeater configuration connect the network and subscriber. á

The UPA 100 consists of an external enclosure that connects to the serial port of an IBM compatible PC. All software is included.
