FRM220-E1-T1-SFP is a fiber media transport for G.703 E1/T1 transmissions. The BNC model provides unbalanced 75 Ohm coaxial E1 connections while the RJ-45 model provides switchable balanced 120 Ohm E1 or 100 Ohm T1 connections over twisted pair wiring. When the FRM220-E1-T1 card is placed in the FRM220 rack with in-band management, the card status, type, version, fiber link status, E1 or T1 link status and alarms for both local card and remote unit can all be displayed. When set for E1 mode, the FRM220-E1-T1 also supports fractional (structured) E1 when connected to a remote FRM220-Data, synchronous data communications converter. In an E1 transmission network where end connection requires synchronous data communication such as V.35 or RS-530 (X.21, RS-449), these units eliminate the need for an extra CSU/DSU. When placed in a single slot chassis and used standalone without management, the card may be configured by DIP switches. .

FRM220-T1-E1-SFP-CH01-LC20A is a standalone fiber to T1/RJ45 or E1/RJ45 converter, including bi-directional SFP 155M module for 20Km.
FRM220-E1B-SFP-CH01-LC20B is a standalone fiber to E1/BNC Converter, including bi-directional SFP 155M module for 20Km.
