Chapter 1. INTRODUCTION CIC-20 LVDS to HSSI Interface Converter While the CDM-600 modem is capable of data rates up to 20 Mbps, its many interfaces do not include the HSSI format. In order to accommodate the HSSI data formats and overhead, the CIC-20 converter attaches to the rear of the modem at the 25-pin data connectors. No external power is required and all settings are made on the CIC-20 using one switch.

Chapter 2. INSTALLATION Perform the following procedural steps: 1 Power down the modem before installing the converter. 2 Remove the four screws, on the sides, and lift off the cover of the CIC-20. 3 The 25-pin female and male D-sub connectors includes four captive screws which can be reached by removing the cover of the CIC-20. 4 Attach the CIC-20 to the CDM-600 modem by mating the two pair of 25-pin D-subs together, then tighten the four captive screws.

Chapter 3. CONNECTOR PINOUTS 3.1 CONNECTOR OVERVIEW The rear panel connectors (shown in Table 1) provide all necessary external connections between the modem and other equipment. Table 1. External Connections Name Ref Connector Type Function Overhead P1 25-pin D (male) Overhead Data Data Interface J1 50-pin, mini-D SCSI-II Data Input/Output HSSI (female) Note: To maintain compliance with the European EMC Directive (EN55022, EN50082-1) properly shielded cables are required for data I/O.
CIC-20 LVDS to HSSI Interface Converter Connector Pinouts Revision 0 MN/CIC20.IOM 3.2 OVERHEAD INTERFACE CONNECTOR (P1) The overhead interface connector is a 25-pin D male interface located on the rear panel of the modem. Refer to Table 2 for pin assignments. Table 2.
CIC-20 LVDS to HSSI Interface Converter Connector Pinouts Revision 0 MN/CIC20.IOM 3.3 DATA INTERFACE CONNECTOR (J1) The Data Interface connector is a 50-pin mini D SCSI-II, HSSI type female. Refer to Table 3 for pin assignments. Table 3.
CIC-20 LVDS to HSSI Interface Converter Connector Pinouts Revision 0 MN/CIC20.IOM Notes: 1. Noted signal function names are non-HSSI defined signals. On Cisco™ routers there is no connection to those pins. 2. TTL - output. 3. TTL or RS232 (active low) input 4. TTL – open collector output. The HSSI interface uses the type of SCSI-2 connector shown in Figure 2. Figure 2.
Chapter 4. OPERATION 4.1 MODEM CONFIGURATION After applying power to the modem, the following configuration changes must be made to the modem in order for it to operate with the CIC-20. 1 Program the transmit and receive data rates to what is desired for Tx and Rx. 2 Set the data interface type to LVDS. The modem itself operates in this electrical format while the converter translates between LVDS and HSSI. 4.2 MODE SELECT The dip switch (S2) selects the functionality of the control signals, CA and TA.
