Yeastar EX30 E1/T1/PRI Expansion Card 1 Port

Yeastar EX30 Expansion

The Yeastar EX30 card is an internal expansion board that adds one onboard E1/T1/J1 digital trunk to supported Yeastar IP PBX platforms. It connects modular S-Series and P-Series systems to carrier PRI or equivalent digital trunks without replacing the chassis. Signaling options include PRI, MFC R2, SS7, and E&M, so the board can follow regional switch types used on E1 and T1 plants. This module is unrelated to wireless access points or Ethernet switches that share similar short model strings.

Key Features

• Single digital trunk span
  One E1/T1/J1 port expands the PBX with a dedicated digital trunk for inbound and outbound carrier traffic.

• Broad signaling support

  • PRI for ISDN primary-rate trunks.
  • MFC R2 variants for multiple countries.
  • SS7 (ITU, ANSI, China) and E&M where required.

• Chassis compatibility
  Designed for Yeastar S100 and S300 plus P560 and P570. Slot capacity depends on the host model, so confirm free EX slots before ordering multiple boards.

• Modular growth path
  Add digital trunks only when call volume or carrier contracts require them, keeping base PBX hardware unchanged.

Why Choose This Expansion Board

• Adds carrier-grade digital trunks without migrating to a larger PBX appliance.

• Supports the signaling set used across African and international PRI deployments.

• Keeps voice infrastructure modular when SIP trunks and digital trunks must coexist.

• Clear host compatibility list reduces returns from wrong-slot accessories.

Additionally, planners should verify that the host license and DSP capacity can terminate the new span. Therefore firmware on the PBX must match Yeastar’s supported release for EX-series boards. However, physical installation requires a powered-down chassis on many models. Consequently, schedule a maintenance window, seat the board fully in the EX slot, then commission the trunk in the PBX trunk settings with the correct switch type and framing. Always follow the official datasheet for slot counts on P560 versus P570 and S100 versus S300.

Network engineers integrating ISDN PRI with SIP endpoints gain a controlled media path through the PBX core. The board presents a single RJ45-style digital interface for the span, while call routing, IVR, and recording remain on the Yeastar software layer. This separation keeps carrier handoff predictable when number ranges and DID maps change.
