Name: 64-port FXS/FXO over 1*E1 PCM Multiplexer
Brand: KDS Telecom
Availability: InStock

KDS-E1P64 is a specialized E1 Transmission Equipment developed by our company, based on independently researched Ultra Large Scale Integrated Circuits.

KDS-E1P64 provides 64 telephone channels (FXS/FXO) interfaces and uses 1 E1 transmission interface to carry the services. The product is designed for 1U 19-inch rack-mount installation.

KDS-E1P64 features an internal automatic time slot allocation function: a time slot is automatically allocated when a phone goes off-hook and is promptly released when on-hook. It allows for a maximum of 31 simultaneous phone calls, offering extremely flexible application configuration.

KDS-E1P64 core circuitry employs a full digital design, features comprehensive alarm functionality, and ensures stable and reliable operation, low power consumption, high integration, and compact size.

1. Core Technology & Design: Utilizes proprietary intellectual property (IP) high-performance integrated circuits; the device is designed for 19-inch 1U rack-mount installation.
2. E1 Interface Standard: The E1 interface fully complies with ITU-T G.703 recommendations, featuring built-in all-digital clock recovery and smooth phase-locked loop (PLL) technology.
3. High Capacity Access: Provides 1 to 64 voice channels, requiring only 1 E1 transmission interface to carry services.
4. Intelligent Time Slot Allocation: Features internal automatic time slot allocation, allowing for a maximum of 31 simultaneous phone calls, with corresponding indicator lights to display the online status.
5. Rich Voice Interfaces: Flexible support for FXO/FXS/Two-Four Wire E&M/Two-Four Wire Audio/Magneto Telephone interfaces; FXO interfaces connect to PBX, and FXS interfaces connect to user telephones.
6. Core Service Functionality: Full-channel support for Caller ID, Reverse Polarity Billing, and Fax functionality.
7. Routing & Interoperability: Supports automatic routing for inter-site dialing (mutual number dialing between sites).
8. NMS & Operations: Optional SNMP or Console network management; features comprehensive alarm functionality, ensuring stable and reliable unit operation.
9. Power Redundancy & Polarity Protection: Offers multiple power supply options and supports dual power backup modes such as AC+DC, AC+AC, and DC+DC; DC power supplies feature automatic polarity detection, eliminating the need to distinguish polarity during installation.
10. Safety & Characteristics: Telephone interfaces include built-in high-standard lightning protection, meeting the GB/T17626.5 (6KV) standard; the unit is characterized by low power consumption, high integration, and compact size.
