– Line Type: the type of DS1 Line implemented on this circuit. The type of circuit affects the number of bits per second that the circuit can reasonably carry, as well as the interpretation of the usage and error statistics. Select fromt he following values: • other(1)—Link is disabled • dsx1ESF(2)—Extended Superframe DS1 • dsx1D4(3)—AT&T D4 format DS1 • dsx1E1(4)—Based on CCITT/ITU G.704 without CRC (Cyclical Redundancy Check) • dsx1E1-CRC(5)—Based on CCITT/ITU G.704 with CRC (Cyclical Redundancy Check) • dsx1E1-MF(6)—Based on CCIT/ITU G.704 without CRC (bit oriented signaling) • dsx1E1-CRC-MF(7)—Based on CCIT/ITU G.704 with CRC (bit oriented signaling) • dsx1E1-Transparent(8)—Based on CCIT/ITU G.703 without CRC (Cyclical Redundancy Check) Configuring the T1/E1 Ports FS6300 NMS User Manual 7 • Configuring the 3196RC Card – Line Coding: The type of Zero Code Suppression used on the link. • dsx1JBZS(1)—Jammed Bit Zero Suppression, in which the AT&T specification of at least one pulse every 8 bit periods is literally implemented by forcing a pulse in bit 8 of each channel. Thus, only seven bits per channel, or 1.344 Mbps, is available for data. This feature is not currently implemented. • dsx1B8ZS(2)—The use of a specified pattern of normal bits and bipolar violations which are used to replace a sequence of eight zero bits. The most common coding for T1 circuits. • dsx1HDB3(3)—This line coding is used with most E1 circuits today. • dsx1ZBTSI(4)—May use dsx1ZBTSI, or Zero Byte Time Slot Interchange. This feature is not currently implemented. • dsx1AMI(5)—Refers to a mode wherein no zero code suppression is present and the line encoding does not solve the problem directly. In this application, the higher layer must provide data which meets or exceeds the pulse density requirements, such as inverting HDLC data. • other(6)—This feature is not currently supported. – Receive Equalizer: The equalization used on the received signal. Long haul signals should have the equalization set for more. Short haul signals require less equalization. – Receiver Sensitivity: The minimum voltage at which the WAN port will sense that the signal is available. This variable is only used if the Receiver Equalization is set to ON. – Line Build Out: The T1 or E1 pulse levels used by the T1/E1 ports: • triState(0)—When the T1/E1 port is not in use, you may want to place the port in tri-state mode. While in this setting, the input lines to the port are placed in high impedance protection mode. • e1pulse(1)—Used when connecting the T1/E1 port to E1 lines. • t1pulse0dB(2)—Strong T1 pulse amplitude. • t1pulse-7dB(3)—Medium T1 pulse amplitude. • t1pulse-15dB(4)—Weak T1 pulse amplitude. – Yellow Alarm Format: The standard used to transmit and identify the Yellow Alarm. • link YellowFormatBit2(1)—Bit-2 equal zero in every channel • link YellowFormatDL(2)—FF00 pattern in the Data Link • link YellowFormatFrame12FS(3)—FS bit of frame 12 – Fdl: implementation of FDL is being used, if any. FDL applies only to T1 circuits. • other(1)—Indicates that a protocol other than one following is used. • dsx1Ansi-T1-403(2)—Refers to the FDL exchange recommended by ANSI. • dsx1Att-54016(3)—Refers to ESF FDL exchanges. • dsx1Fdl-none(4)—Indicates that the device does not use the FDL. If one of the E1 line types has been selected, set Fdl to dsx1Fdl-none(8). 3. Click Submit to commit your changes.

In the T1-E1 Port Configuration window for the selected link, click on Modify Test Settings. 2. Edit the desired options: – Force Yellow Alarm: The standard used to transmit and identify the Yellow Alarm. • linkYellowAuto—Do not force the transmission of a yellow alarm. But, yellow alarm may be automatically transmitted. • linkYellowOn—Force the transmission of a yellow alarm even if the received signal is in frame. • linkYellowDisable—Do NOT transmit a yellow alarm even if the received signal is out of frame. – Loopback Configuration: The loopback configuration of the DS1 interface. • dsx1NoLoop(1)—Not in the loopback state. A device that is not capable of performing a loopback on the interface shall always return this as it's value. • dsx1PayloadLoop(2)—The received signal at this interface is looped through the device. Typically the received signal is looped back for retransmission after it has passed through the device's framing function. • dsx1LineLoop(3)—The received signal at this interface does not go through the device (minimum penetration) but is looped back out. • dsx1OtherLoop(4)—Loopbacks that are not defined here. – Send Code: The type of code is being sent across the DS1 interface by the device. • dsx1SendNoCode(1)—Sending looped or normal data • dsx1SendLineCode(2)—Sending a request for a line loopback • dsx1SendResetCode(4)—Sending a loopback termination request – Error Injection: Force an output error to see if the o...
