Ethernet Bridge over E1(GFP)
- HDLC & GFP
- MTU 2046bytes
- Unuframed E1
Description
The FRM220A-Eoe1/G(S) is an Ethernet over E1 Bridge for cost-effective connection of 10/100Base-TX or 100Base-FX
LANs over a single E1 transport. By using GFP (Generic Framing Procedure) or standard HDLC encapsulation, the
FRM220A-Eoe1/G(S) is able to transmit up to a 2M bits Ethernet over an E1 link. The FRM220A-Eoe1/G(S) supports an E1
attenuation of up to 43 dB on twisted pair or coax cable, which provides an approximate operating range up to 2km
(using 22AWG). The FRM220A-Eoe1/G(S)fully meets E1 specifications including ITU-T G.704 and G.823. The Ethernet
copper interface supports auto-negotiation and auto MDI/MDIX, allowing plug-and-play Ethernet connection without
any additional configuration. When placed in FRM220A system, the Ethernet may be aggregated to the chassis’s built in
Ethernet switch. When placed in a single slot chassis and used standalone without management, the card may be
configured by serial terminal.
