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:
a. 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.
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 3 CCIS links per system is allowed.
PN-2BRTC
This card has two circuits of Basic Rate interface (2B+D) and provides connectivity for Voice, High
Speed Data, Switched Video and G4 Fax calls to be placed and received via ISDN Basic Rate (BRI) to
the ISDN Network. The BRTA-C card has built-in DCH (D channel handler) and has a ST interface. A
locally provided NT1 device is required to connect to the ISDN Network. One BRI trunk provides two
incoming/outgoing voice connections and (or) two 64k bps channels for high-speed data. This card is
used for BRI trunks from the Telco to the PBX.
PN-4BRTC
This card has four circuits of Basic Rate interface (2B+D) and provides two 2-channel PCM digital lines.
This card is used for BRI trunks from the Telco to the PBX.
PN-CFTB
The CFTB card is a 6 Party Conference card. One card can control a conference of up to ten
participants. This card occupies 10 time slots per one card.
PN-CFTC
The CFTC card is a 32 Party Conference Trunk card. One card can control a conference of up to 32
participants. Two Conference methods are available: Group Call and Meet-Me Conference. This card
occupies 32 time slots per one card.
