Anleitung Zusammenfassung
Swap is available only on switch 7 and is applicable only on the 12 port model. Depending on the services provided by your carrier for voice and data, you may need to reassign the FXS timeslots of the 12 FXS port model. Timeslots 13 to 24 will be assigned in order to allocate data to the lower timeslots. The DIP switch setting shown in the illustration above is for Switch S7 ONLY. ADCP-62-023 © 1998, ADC Telecommunications, Inc. Issue 1, September 1998 External DIP Switches Configuring the ICX-250 31 External DIP Switches The ICX-250 is equipped with five external DIP switches (four - 12 dip switches, and one - 7 dip switch) located on the rear panel of the unit. These switches are used for Data Port and T1 Configuration. Each switch is set to a preconfigured factory setting when shipped. The illustration below outlines the location of these DIP switches. Note: The individual switches on each switch assembly operate independently of one another. ICX-250 - Rear Panel Switch numbers S1 through S5 are shown on the board within the unit.

Description: S1 position 4 is used to select the T1 clock source. Factory Setting: LINE Line: Clock for the T1 interface will be recovered from the line (receive signal). Internal: Clock for the T1 interface will be taken from an on-board 1.544 MHz clock meeting the Stratum 4 requirements. Note: Failure of external clock causes unit to switch to internal clock. When external clock is restored, the unit will switch back to external clock source. Issue 1, September 1998 © 1998, ADC Telecommunications, Inc.
