Central Site Remote Access Switch 89HARDWARE I NSTALLATIONAdapter SettingsENCRYPTION A DAPTER SETTINGSDES/RSA AdapterThe DES/RSA adapter is available in the United States and Canada only. The adapter has a set ofeight dip switches in a switch block labelled SW1. Set these dip switches to map the encryptionadapter memory at D800:The adapter has one jumper (J1), which must be installed!MVIP SETTINGSThe following adapters have MVIP connectors:• PRI-23,• PRI-23/30,• DM-8,• DM-24,• DM-24+, and• DM-30+In order to establish an MVIP bus, follow this process:1. First, select slots for all MVIP adapters. If you are using both PRI and DM adapters, begin witha PRI adapter, and then select slots alternating PRI and DM adapters as described in SelectingSlots for Adapters.2. Next, terminate the MVIP jumpers on both the first and last adapter in the MVIP adapter series.(All other MVIP jumpers on the adapters between these two should be left unterminated).• To terminate the MVIP bus for the PRI-23, place the jumpers vertically on JP9.• To terminate the MVIP bus for the PRI-23/30, place the jumpers vertically on JP9.• To terminate the MVIP bus for the DM-8, place jumpers horizontally on J5 and J6.• To terminate the MVIP bus for the DM-24, turn switch blocks S1 and S4 “ON”.Note: DM-24 adapters may have either toggle or slide switches. In either case, theswitch is “ON” if it is toggled or slid to the right. All four switches shouldalways be set in the same direction.• To terminate the MVIP bus for the DM-24+ or the DM-30+, place the four switches inswitch block SW5 to the “ON” position.3. Install MVIP adapters into pre-selected slots.4. Install MVIP ribbon cable. Refer to Connecting Adapter Inter-board Cables.5. Install TDM ribbon cable. Refer to Connecting Adapter Inter-board CablesIn order to improve signal quality (which in turn results in higher modem-connection rates), youshould terminate the MVIP bus at both ends as recommended in step (2). However, not all systemconfigurations support this. Note that PRI-8, PRI Expansion and BRI boards do not support MVIPtermination.Note: MVIP termination at both ends (step 2) also applies to six PRI-23/30 configurations.SW1 Memory Mapped Address 1 2 3 4 5 6 7 8D800 OFF OFF OFF OFF OFF OFF OFF ON
