ESB2 card supplies Abilis with 4 synchronous ports you can configure up to 2,5 Mbps. They are generally used for CDN or HDSL connections.

Figure 2.13. ESB2 card

As shown on the picture, the ESB2 card can hold up to 4 modules:

The modules are plug-to-plug compatible and can be hold in any arrangement. The external devices are connected to an “octopus” cable connected to the ESB2 card. This cable has 4 DB15 female connectors numbered from 0 to 3 which correspond to the 1 to 4 modules and a HDB-62 female connector to connect the card. These connectors will be connected to the corresponding adaptation cables V24/V35/X21/E1.

Each DB15 connector has 15 pins. The HDB-62 connector has 62 pins.

Figure 2.17. “Octopus” cable

The adapter cable is made by 7 twisted pairs. The cable is shielded.

	Note
	Pins 21 and 42 are not connected and can be used for the insertion key.

The port pins will have different meaning in fuction of the interface modules installed as shows in the following table:

Abilis software numbers the synchronous ports as shown in the table:

2.8.1.1. How to connect modules

The X1 connector of the each interface module is inserted into X3, X5, X7 or X9 (depending on the module number) connector of the ESB2 card. The X2 connector of the each interface module is inserted into X4, X6, X8 or X10 (depending on the module number) connector of the ESB2 card.

Figure 2.18. Placement of the module connectors on the ESB2 board

Each module has two side:

• the board side which is connected via X1 connector (50 pins);

• the line side which is connected via X2 connector (26 pins).

The CTI boards are machines to deal with ISDN and VoIP phone communications. They provide TDM and VoIP switching, voice codification and packetization, echo cancellation.

2.8.2.1. CTI-HA

CTI-HA cards are obsolete.

CTI-HA cards host 4 slots for DSP modules, each of them can hold 0, 1, 2 or 4 DSP (Digital Signal Processor, chip for voice compression/packetization). On the right side of the card there is a slot for a daughterboard (QPRI, BRI-4 or BRI8 modules , respectively for ISDN Primary Rate Interface (PRI) or Basic Rate Interface (BRI) support).

Figure 2.20. CTI-HA

On the upper side of the CTI card there is a H.100 interface, which enables the connection of several CTI cards between each other (besides through PCI bus) . The H.100 bus creates a system with a capacity of up to 2048 simultaneous calls.

2.8.2.3. BRI8 and BRI4 Module

BRI8 module, assembled on a CTI card, makes available 8 ports BRI ISDN Basic Rate (configurable S0/T0) ports). BRI4 and BRI8 modules are almost identical, but BRI4 supports only 4 ports (it uses a different chip).

Figure 2.21. BRI4 Module

	Warning
	Although only one PCI slot is used for the electrical connection on the external part of the cabinet, the eight BRI ports take as much place as two slots (mechanical connection).

The BRI8 and BRI4 modules mount four RJ45 sockets with the following pinout:

Table 2.8. BRI-HFC – RJ45 pinout

Pin	Signal
1	N.C.
2	N.C.
3	Rx + (inbound)
4	Tx + (outbound)
5	Tx - (outbound)
6	Rx - (inbound)
7	N.C.
8	N.C.

You can configure every port at logical level like NT (Network Termination) or TE (Terminal Equipment).

The BRI ports permit the use of impedance matching adapter.

The QPRIX is a stand-alone card, it has 4 primary interfaces (ISDN-PRI) and supports up to 16 DSP for 64 compressed calls. Besides echo canceller (EC) is available up to 32 ms but it can raise up to 128 ms in the version with the additional Octasic chip (EEC).

Through H.100 bus it can also be connected to other cards of the CTI category.

Figure 2.22. QPRIX

For the ISDN-PRI (S2M) interfaces no standard physical port is specified. The Abilis QPRIX use RJ45 sockets with the same signal arrangement as the one used to access to BRI NT:

Each interface presents a 120 ohm balanced impedance. Each port can be configured as NT (Network Termination) or TE (Terminal Equipment).

The PB22X is a stand-alone card, it has 2X ISDN Primary Ports (ISDN30) and 2X ISDN Basic Ports (ISDN2)

Through H.100 bus it can also be connected to other cards of the CTI category.

The Abilis PB22 use RJ45 plugs with the following pinout for ISDN-PRI (S2M):

The Abilis PB22 use RJ45 plugs with the following pinout for ISDN-BRI:

The PB44X card has 4 primary interfaces (ISDN-PRI) and, by means of a daugtherboard (BRI4ADD, see photo), 4 ISDN Basic Rate (ISDN-BRI) interfaces. All interfaces are freely configurable as NT / TE.

It supports up to 16 DSP for 64 compressed calls and can be connected to other CTI cards through the H.100 bus.

	For information about the connection between Abilis and ISDN Basic Rate Interface (BRI) lines refer to Section 3.2, “ISDN Basic Rate Interface (BRI) connection”.

The PB44X cards use RJ45 plugs with the following pinout, either on the main board (4 PRI ports) or on the extension (4 BRI ports).

Each PRI interface presents a 120 ohm balanced impedance. Each port can be configured as NT (Network Termination) or TE (Terminal Equipment). The BRI ports have to use an impedance matching adapter.

	Warning
	Although only one PCI slot is used for the electrical connection on the external part of the cabinet, the additional 4 BRI ports occupy an additional slot (for mechanical connection only).

The PB44 card has 4 primary interfaces (ISDN-PRI) and, by means of a daugtherboard (BRI4ADD, see photo), 4 ISDN Basic Rate (ISDN-BRI) interfaces. All interfaces are freely configurable as NT / TE.

The PB44 cards use RJ45 plugs with the following pinout, either on the main board (4 PRI ports) or on the extension (4 BRI ports).

Each PRI interface presents a 120 ohm balanced impedance. Each port can be configured as NT (Network Termination) or TE (Terminal Equipment). The BRI ports have to use an impedance matching adapter.

The POTS cards belong to the CTI family and are used to connect analog telephone to the Abilis system. POTS are available with 4 , 8 or 16 FXS (BCA) interfaces. Through the H.100 bus, when installed on the same Abilis, several POTS cards behave like a single module (it works also with CTI or BRI-HFC cards). In this way Abilis becomes a powerful PBX system.

Figure 2.28. POTS

POTS cards have four RJ45 sockets. Each socket is to be used with an octopus cable (one RJ45 plug <-> four RJ11 plugs). Each RJ11 is for one telephone.

The octopus for POTS use the following pinout.

	Note
	A variable delay to the start of ring signals is used to prevent a current overload in case of multicast groups with large number of Pots ports. The delay is in range of 20 to 140 msec.
