ISDN Primary Rate Interface Card (T-point) - PRI (VB-44540)

T-point primary rate interface requires a DSU for connection to the carrier circuit. A Network Sync
card is also required.
A lightning arrester is built into the PRI card.
This supports T-point Integrated Services Digital Network (ISDN) Primary Rate Interface (PRI)
(23B+D/24B:1544kbps) (30B+D/31B:1984kbps) and also S-point ISDN Primary Rate Interface.
The PRI card can be set to support either 8, 16, 23/24 or 30 channels. When the card is set for 16
channels, the card logically occupies 2 flexible card slots. When the card is set for 23/24 or 30
channels, the card logically occupies 3 or 4 flexible card slots.
Unlike other most other cards, due to the interaction between card slots, the PRI card must be
installed in selected flexible card slots. Up to 3 PRI cards can be installed in a single cabinet. A fully
configured 6-cabinet system can support up to 18 PRI cards.

Q-sigInterface Card - PRI (VB-44540)

Digital Networking using Q-sig line is available using PRI card.

ISDN Basic Rate Interface Card (T-point) - BRI (VB-44530)

This supports T-point Integrated Services Digital Network (ISDN) Basic Rate Interface (BRI)
(2B+D:144 or 192kbps). This card can be installed in any flexible slot.
The functions supported are as follows:
Dial Type Enblock setting and enblock setting at the sub-address.
Information transferring capability (speech and data) at the CO trunk.
The BRI T-Point connects through a DSU to the T-point ISDN Basic Rate Interface.
A lightning arrester is built into the BRI card.
E&M Trunk Card - E&M (VB-44560) (HK/TW)
This card supports E&M type private line interface (Speech pass 4W/2W, Control line 4W). The
signaling methods that are supported include Immediate and Wink methods.
When installed in any flexible slot, the E&M Trunk Card supports call signal detection and answer
from other PBX or carrier equipment, calling to the E&M private line, dial sending and speech.
Each E&M card includes 4 circuits.
An internal -48V Power Supply (VB-44022) must be installed in the same cabinet with the E&M Trunk
Card.
The E&M interface can connect to another PBX with E&M capability. However, this unit does not
support connection to an E&M that provides only Type 1.
This unit contains a built-in lightning arrester; however, external safety devices (available from
standard telecommunications suppliers) are required when installing outside the building.
AC15 Trunk Card - E&M (VB-44570) (UK only)
This card supports AC15 type private line interface. The AC-15 private line is designed to operate with
the 2280Hz carrier used in U.K.. Each line consists of four signal lines:TX1 and TX2 for transmission,
and RX1 and RX2 fore reception.
