This port is labeled Voice. See Appendix C for pinouts of this connector. This port manages the flow of FXS voice traffic over the network. Each port encodes analog (voice, VF) signals to a digital bitstream at the local system for transmission over a T1 network. It also decodes the digital signals to analog at the remote system.
Model No. Running Head Figure 6-1. Typical FXS port Main Screen The bottom highlighted line of this screen shows various actions that you can perform from this screen. You perform the desired action by pressing the associated uppercase letter key. Table 7-1 summarizes these actions. For example, after you configure the FXS port ports, press “s” to save your settings. Table 7-1summarizes the configuration settings for the FXS ports, along with the available and factory-default option settings.
WAN The WAN setting identifies the WAN link assigned to this port. If you choose wan, you also must select the desired port (w1-1 through w1-4) of a WAN port for transmission over a T1 link. It is not necessary to assign all ports of the same FXS port to the same WAN link, or to contiguous time slots on a WAN link. TS The TS setting identifies the time slot on the WAN link to which this port is assigned. Values range from 1 to 24 for T1 links.
Model No. Running Head Tx TLP The Transmit TLP setting controls the amount of gain or loss added to a voice signal from the CPE before it is encoded to digital PCM. To increase the signal level, set the Tx TLP setting to a negative value (i.e., the more negative the number, the more gain is added). To decrease the signal level, set the Tx TLP setting to a positive value (i.e., the more positive the number, the more the signal level is decreased).
PATTRN The Pattern field selects an outgoing test pattern for the current port. The test pattern is generated by the system and sent to the selected port. You can select a different pattern for each port. The none option disables the test pattern. The D-mW (Digital milliwatt) option sends a 1 kHz tone at 0.0 dBm. The setting of the Rx TLP setting affects the D-mW signal level. 6.3.

Chapter 9 HSU Ports 9.1 Introduction This chapter provides information regarding the configuration and troubleshooting for the IMACS-200 High-Speed Data Ports. The IMACS-200 provides two High-Speed Data ports which connect via an RS-530 interface DB-25 connector, and employ V.35 standard for high-speed synchronous data exchange. The HSU ports allow you to connect high-speed data terminal equipment (DTE) to WAN links and/or other HSU ports. 9.2 HSU Ports The IMACS-200 supports two V.35 CPE devices.
Model No. Running Head 9.2.1 HSU Port Cables For connecting HSU Ports for DTE and DCE transmit clocking, use the PRM-1261M cables. 9.3 HSU Card User Screens and Settings The HSU Cards permit configuration and operation through use of several user screens and optional settings. 9.3.1 HSU Card Main Screen You must configure the HSU ports for operation. Configuration can be performed from the HSU Main Screen, which is shown in Figure 9-1. Figure 9-1.

Updates certain time-related information fields that are not automatically updated (i.e., performance and test data). Copies the contents of the current column to the next column. Useful if you change a lot of entries in one column and want to repeat those changes in subsequent columns. Initiates and monitors testing of all HSU Card ports.
Model No. Running Head DSR CTS High Definable High Definable Low High WAN The WAN setting identifies the WAN port to which the output of this port is directed. I (the options are w1-1 to w1-4). MODE The Mode parameter allows you to identify how the HSU port appears to the device on the other end of the interface cable. The dce option causes the port to be recognized as a DCE (data circuit-terminating equipment) device. The dce option is always chosen in the first offering of the IMACS-200.
RATE The Rate setting allows you to select the bandwidth for all time slots assigned to this port. The available options are 56k or 64k. This selection is multiplied by the number of time slots assigned to the port, to define the overall port speed. For example, if you choose 64k as the port Rate and assign four time slots to that port, the overall port speed is 256 kbps. Tx CLOCK The Transmit Clock (Tx CLOCK) setting identifies the clock source for the SD (send data) signal from the external CPE.
Running Head Model No. DATA PLRTY The Data Polarity (DATA PLRTY) option allows you to either send all data bits to the network as normal ones and zeros, or to invert all bits in the transmitted data stream. Choose norm (normal) to leave the transmitted data intact; or, choose inv (inverted) to invert all outgoing data. This can be helpful in ensuring minimum-ones density transmission over T1 links when the data contains long strings of zeros.
Figure 9-3. Local DTE Loopback Choose the net (network) setting to loop the incoming data from the network back toward the far end. This loopback is shown in Figure 9-4. It tests some of the local HSU Card circuitry, the local system common cards, the WAN link card, the far-end HSU port and CPE device, and the WAN link between the two sites. The net setting also drops the Data Set Ready (DSR) control signal output on the HSU port. Figure 9-4.
