The ByteGrabber II-A card turns your PC in to a ISDN BRI protocol analyzer for U or ST interface lines. Supports layer 1, 2, and 3 and provides decodes to the screen of the PC. Packets are displayed as separate items in a list. Activations and bit errors, as well as the content of any embedded operations channel (ECO) messages, M-bits for U-Interface and S&Q bits for ST-Interface, TEI assignments, SPID negotiations, B channel setup and other call control operations are displayed. Detailed layer 1 messages plus layer 2 & 3 decodes and raw packet data permits rapid troubleshooting for the experienced technician. Data is collected from the 2B+D in both directions and passed to the PC via the ISA Bus. The ISDN data can be saved to disk for analyzing at a later time. The unit connects in series with the Network and USER anywhere on the U interface or bridged to the S/T interface. ISDN installers and troubleshooters typically use the ByteGrabber II-A to resolve disputes between the phone company and the user. A technician can be sent to the trouble site to capture data that can be sent to an experienced technician or specialist for evaluation. ISDN equipment developers use the card for looking at real-time data in order to determine if their equipment is performing according to specifications.

ISDN InterfacesISDN "U" 2B1Q interface (serial "in-line") via Network
and User RJ45 jacks. Decode SpecSupports layers 1,2 and 3 per Q.921/Q.931. Line TypesANSI (U.S.) or ETSI (European) Line Bypass RelayIn case of power failure or software detected problem, the ISDN BG2 "U" interface is bypassed, relays provide a direct connection from the user to the central office. This is not required with the S/T interface. Line TransparencyIn the "U" interface mode, the BG2 appears "transparent" to the line. It does not react to maintenance codes, but passes them on to the other side. If the user side goes down the network side goes down too. If the network (CO) side goes down, the user side goes down. This most accurately mimics the operation of a normal ISDN line. NOTE: This is not applicable to the S/T interface where the BG2 is not inserted "in-line" but makes a "bridged" connection. Loop PositionBG2 may be placed in the ISDN "U" loop at any position up to 18,000 feet on either side of the BG2. However for proper operation with line bypass relay, the total length should not exceed the telco limit of the loop Sealing Current or Line PowerTransparent - LED indication if sealing current or line power is present.
