PN-AUCA This circuit card is used to either control two single line telephones for off-premise extensions or for 2-
line Direct Inward Dialing trunks. Also, this card will connect to single telephones for Power Failure
Transfer.
PN-2ODTA The 2ODTA card is a two or four wire tie line card that mounts in any LT slot in PIM 0 to 7. This card
provides analog tie line service for standard PBX networking or CCIS.
SPN-24DTAC This circuit card is a 24 channel 1.5 Mbps digital interfacing trunk card which also supports the interface
between ISDN lines and CCIS lines with 1.5 Mbps AMI. The following circuit cards may be used in
conjunction with the 24DTA:
SPN-SC01 - This circuit card controls the signal link (D channel) when Integrated Services
Digital Network (ISDN) PRI (Primary Rate Interface - 23B+1D) is employed in the system.
This package will support one signaling link on a single DTA package. A maximum of 8 ISDN
spans are allowed per system.
SPN-SC00 - This circuit card controls signal links when Common Channel Interoffice
Signaling (CCIS) is employed in the system. This package will support one signaling link on a
single DTA package. A maximum of 8 CCIS links per system is allowed
SPN-24PRTA This circuit card is a 24 channel 1.5 Mbps digital interfacing trunk card that also provides a built-in D-
Channel Handler (DCH). This package provides one DTI span with ISDN Data Link on a single
package. A maximum of 8 ISDN links per system is allowed per system.
SPN-24CCTA This circuit card is a 24 channel 1.5 Mbps digital interfacing trunk card that also provides a built-in C-
Channel Handler (CCH) for CCIS. This package provides one DTI span with CCIS Data Link on a
single. A maximum of 8 CCIS links per system is allowed per system.
SPN-30DTC This circuit card is a 30 B-channel, 2 Mbps E1 digital interfacing trunk card (2.048 MHz). Typical E1
applications apply to any CCIS, Q-SIG, and TIE Line application via continuous property. Complies with
U-LAW PCM voice coding standard used in North America.
Note: Does not support A-LAW coding used in Europe, Mexico and South America.
The following circuit cards may be used in conjunction with the 30DTC:
SPN-SC01 - This circuit card controls the signal link (D channel) when Integrated Services
Digital Network (ISDN) PRI (Primary Rate Interface - 30B+1D) is employed in the system.
This package will support one signaling link on a single DTA package. A maximum of 4 ISDN
spans are allowed per system.
SPN-SC00 - This circuit card controls signal links when Common Channel Interoffice
Signaling (CCIS) is employed in the system. This package will support one signaling link on a
single DTA package. A maximum of 3 CCIS links per system is allowed.
