HY120DE/420DE Digital Telephony Cards( EC Module Optional)
New version, our second generation digital cards.
Supporting EC Module with Octasic EC chip.
Hardware channel switching.
More efficient processing ability
Supporting Hardware HDLC.
Providing E1/T1/J1 support in one card
Compliance with international telecommunications standards
Specifically designed for the Asterisk platform, available for Freeswitch, Yate and other open source project.
Efficient: Optimization of DMA transmission and hardware switching.
Clock: Support the master-slave clock. So several different carriers can be connected simultaneously.
Interfaces: Mixing T1/E1/J1 have been supported.
Line coding : HDB3 / AMI / B8ZS
Frame format : CRC4 / non-CRC4 / ESF / D4T1 / E1
HDLC Processing: Independent hardware HDLC transceiver
Driver optimization: Specifically optimization for high volume data transmission in drivers
This series include the following three models:
his series provides
full-duplex telephone card data with 1 6.384M transfer rate or 120-channels
voice communications. Each machine can support multiple cards, particularly
suitable for the development of Asterisk-based applications.
