Yeastar EX30 1 Onboard E1 T1 PRI Port

The Yeastar EX30 1 Onboard E1 T1 PRI Port is a telephony expansion board designed to add one E1/T1/J1/PRI interface to compatible Yeastar PBX systems. It provides a physical interface for connecting a business telephone system to an E1, T1 or PRI service supplied by a carrier or other compatible telephony equipment. Yeastar documents the EX30 as an expansion board with one onboard E1/T1/PRI port, with current P-Series documentation identifying support for the P560 and P570.

The EX30 is suited to organizations that require digital trunk connectivity for business telephony, including offices, enterprises, call centres and telecom deployments. For customers in Kenya, compatibility with the exact PBX model, carrier service, signalling, framing and line coding should be confirmed before purchase.

Product Features

One E1/T1/PRI Port

The Yeastar EX30 provides one onboard E1/T1/PRI port, allowing a compatible PBX to connect to an E1, T1 or PRI trunk. Yeastar identifies the EX30 specifically as an expansion board with one E1/T1/PRI interface.

E1, T1 and J1 Support

The interface supports E1, T1 and J1 trunk types where supported by the PBX configuration and carrier service. E1 uses 30 B-channels plus one D-channel, while T1 uses 23 B-channels plus one D-channel. J1 is the Japanese variant of T1.

PRI Trunk Connectivity

E1/T1/J1 is commonly associated with Primary Rate Interface (PRI), an ISDN access method used for digital voice and signalling. The EX30 can therefore provide a digital trunk interface for supported business telephone deployments.

Digital Carrier Integration

The EX30 can connect a compatible Yeastar PBX to an ISDN PRI/E1/T1 service, subject to the requirements of the carrier and the PBX configuration.

Modular PBX Expansion

The EX30 forms part of Yeastar’s modular PBX architecture. It allows supported systems to add physical telephony interfaces without replacing the entire PBX. Yeastar describes its P-Series and S-Series platforms as using modular expansion boards and telephony modules for additional interfaces.

E1/T1 Trunk Configuration

The compatible PBX can be configured according to the carrier’s supplied trunk parameters, including interface type, signalling, framing and line coding. Yeastar’s documentation provides separate configuration options for E1, T1 and J1 services.

Product Specifications

• E1/T1/PRI Ports: 1 onboard port
• Supported Trunk Types: E1, T1, J1/PRI, subject to supported PBX configuration
• Application: Digital telephony trunk expansion

Yeastar documents E1 options including CRC4 and different framing settings, while T1/J1 configurations can use options such as ESF or D4 depending on the service. Line coding options also vary by interface type.

Configuration-Dependent Information

The actual E1/T1/PRI configuration depends on the PBX model, carrier service and trunk specifications. Parameters such as signalling, framing, line coding, D-channel configuration and interface type must match the requirements supplied by the carrier.

For this reason, these parameters should not be presented as fixed specifications of every EX30 installation.

Compatibility

The Yeastar EX30 must be installed in a compatible Yeastar PBX.

Yeastar’s current P-Series documentation states that E1/T1/J1 trunking is supported on the P560 and P570, with at least one EX30 expansion board required to add an E1/T1/J1 interface. The P560 supports one expansion board, while the P570 supports two.

Yeastar documentation for the S-Series also identifies the EX30 for E1/T1/J1 expansion on the S100 and S300. Therefore, when selling an EX30 for an S-Series installation, the exact PBX model and documentation version should be checked before ordering.

Before purchasing, confirm:

• Exact Yeastar PBX model
• PBX hardware/version
• Available expansion-board slot
• E1, T1 or J1 service required
• Carrier signalling
• Framing requirements
• Line coding
• D-channel requirements
• PRI/E1/T1 cable requirements
• Required trunk configuration

Configuration and Installation

The EX30 is installed as an expansion board in a compatible Yeastar PBX. For an E1/T1/J1 trunk installation, Yeastar recommends connecting the appropriate crossover cable between the PBX interface and the ISDN provider’s equipment and then configuring the trunk according to the carrier’s specifications.

Configuration may include:

• Interface type: E1, T1 or J1
• Signalling type
• Framing
• Line coding
• D-channel
• Signalling role
• Codec
• Echo cancellation
• Other carrier-specific trunk parameters

The PBX and carrier configuration must match for the digital trunk to establish correctly.

For business installations, professional configuration is recommended where the EX30 is being integrated with an existing carrier PRI/E1/T1 service.

Applications

Business Offices

The EX30 can provide digital trunk connectivity for organizations using a compatible Yeastar PBX with an E1/T1/PRI service.

Enterprise Telephone Systems

Businesses requiring digital carrier connectivity can use the EX30 to expand a supported PBX with an E1/T1/J1 interface.

Call Centres

Call centres with compatible digital trunk services can integrate E1/T1/PRI connectivity into their supported Yeastar PBX environment.

Telecom Deployments

The EX30 can be used in business telephony and telecom deployments where a compatible Yeastar PBX needs a digital trunk interface.

PRI Migration and Integration

Organizations using traditional digital carrier services can integrate those services with a compatible Yeastar IP PBX.
