Type:FCC-E1O4F1R2/FCC-E1F1S4R2 Message

Description:E1-4 * telephone+FE+2RS-232/422/485/dry connect Support 4U rackmount

Product Description
              This device is a desktop there 4U rack card type which provides telephone outputs 1-4 1 Ethernet (bandwidth 2M) +2 way RS232 / 422/485 (or 4-way RS232 / 422/485). Equipment electrical part for the whole digital circuits machine reliability stability low power consumption high integration small size easy installation and maintenance. Many customers are telecommunications operators E1 leased lines used in computer networking this equipment can be rented at the E1 line opened a few road phone you can make free calls between headquarters and branch offices of this.
Functional Properties
