5 Switch Interface Administration Digital Interfaces Intuity™ CONVERSANT® System Version 7.0 Administration 585-313-501 Issue 3 January 2000 327 The list below shows the LSE1-specific fields:~ Idle Code ~ A-LAW or MU-LAW ~ CRC The list below shows the LST1-specific fields: ~ CSU Distance 3 Change any of the parameters as described in Assign an ISDN-PRI Layer 1 to Digital Circuit Cards on page 317 . 4 Press F3 (Save). The system changes the specified parameters for the selected circuit card. Display ISDN-PRI Layer 1 Parameters The circuit card must first be assigned to the ISDN-PRI Layer 1 protocol to use this procedure. See Assign an ISDN-PRI Layer 1 to Digital Circuit Cards on page 317 for more information about making the initial assignment.

Initially, all fields are populated with the default values for the circuit card number entered. The Card Number: field is blank in Figure 159 on page 328 . After you enter the circuit card number, certain fields disappear depending on the configuration of the selected circuit card. The LSE1-specific fields are: ~ Idle Code ~ A-LAW or MU-LAW ~ CRC The LST1-specific fields are: ~ CSU Distance The LST-1 specific field is: ~ CSU Distance The system displays the parameter values for the selected circuit card. 3 Press F6 (Cancel) to return to the ISDN-PRI Layer 1 menu.

See Equipment State on page 150 in Chapter 3, Voice System Administration , for additional information. If you change digital protocol assignments on the voice system, you must make the change on the switch as well. Use the following procedure to unassign the ISDN-PRI Layer 1 protocol to a digital circuit card: 1 Start at the ISDN-PRI Layer 1 menu (Figure 156 on page 316 ) and select: The system displays the Unassign Card: ISDN-PRI Layer 1 window (Figure 160 on page 331 ). > Unassign Card

The system removes the ISDN-PRI Layer 1 assignment from the selected circuit card. 4 Press F6 (Cancel) repeatedly to return to the Digital Interfaces menu.
5 Switch Interface Administration Digital Interfaces Intuity™ CONVERSANT® System Version 7.0 Administration 585-313-501 Issue 3 January 2000 332 E1 PRI Using the ACULAB Protocol Converter With the use of the ACULAB protocol converter card to support the United Kingdom’s DASS2 and DPNSS protocols, it is no longer necessary to assign an SP card to PRI for use with the E1 PRI protocol. The D-channel processing can now be performed on the AYC21 circuit card leaving the SP circuit card available for other uses. Countries that require the use of an Aculab Protocol Converter Card (for example, the United Kingdom) must connect the network, the AYC21 circuit card, and the Aculab Converter Card (Figure 161 on page 333 ).

Note:Some parameters on the switch side may require that you stop and restart the voice system once you have made changes. For example, when changing the frame format from D4ZCS to ESF, your PRI link to the switch may not come up if you have not stopped and started the voice system. See Stop the Voice System on page 136 and Start the Voice System on page 139 in Chapter 3, Voice System Administration . • T1 E&M Options The following options should be set on the E1/T1 circuit card when it is connected to an AT&T 4ESS:~ Wink Timing: 230 msec ~ Maximum Digits in Called Number: 4 is typical ~ Post-wink Delay: 80 msec
