PN-4DITB
This circuit card is a DID line trunk card which supports the functions of four DID line trunks. This card
provides the following functions:
a. This card is equipped with Direct Inward Dialing (DID) function.
b. This card is equipped with loop detection functions, sending reverse signal, and
DTMF to DP conversion.
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:
a. 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.
b. 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.
