SPECIFICATIONS

RAD Data Communication's FCD-T1L T1 CSU provides single port V.35 data access to a T1 or fractional T1 services

? FCD-E1L and FCD-T1L are managed access units, which can be used as rate and interface converters for E1/T1 and Fractional
E1/T1 services.
? FCD-E1L and FCD-T1L support a single or dual user interface that can be either n x 64 kbps serial data interface or Ethernet LAN interface allowing LAN-to-LAN connectivity over TDM media.
? FCD-E1L and FCD-T1L also operate opposite RAD's modular DXC (DACS) products or other vendors' E1/T1 equipment, to support multilink star applications, such as access to SDH networks. The DXC and the FCD units operate together with a centralized SNMP network management.
? The E1 interface is compatible with virtually all carrier-provided E1 services and meets ITU recommendations G.703, G.704,
G.706, G.732, G.823 and G.826. It supports both 2 and 16 frames per multiframe, with or without CRC-4. It can also accept a 2048 kbps data stream and convert it to an ITU-T Rec. G.703 unframed signal for transport over the E1 main link. Line code is HDB3. The integral LTU ensures a range of up to 2 km/1.2 miles and is soft-selectable.
? The T1 interface is compatible with virtually all carrier provided T1 services, including ASDS from AT&T and complies with
TR-62421. The T1 interface supports D4 and ESF framing formats. Zero suppression over the line is selectable for either transparent, B7ZS or B8ZS.  The user-selectable integral CSU ensures a range of up to 1.3 mile.
? Timeslot assignment is programmable, allowing data from each data port to be placed automatically into consecutive
