Fractional - T1/E1 - A fractional line is subchannel of a full T1/E1<br />
line. There are 24/31 fractional T1/E1 lines, each with a<br />
b<strong>and</strong>width of 64 kbps. This is an economical measure to fit the<br />
requirements where the full DS1 is not needed. Individual DS0<br />
slots may be switched to different services or locations. The user<br />
may provide a full DS1 from each end of the circuit, but the<br />
central office extracts only those DS0s that are paid for <strong>and</strong><br />
routes them to the required service or location.<br />
FRAD - frame relay assembler/dissembler<br />
FRAGO - fragmentary order<br />
FRAM - ferro-electric r<strong>and</strong>om-access memory<br />
Frame - (Data) - In bit-oriented protocols, data is formatted in frames<br />
for transmission. Each frame consists of a start flag followed by<br />
an address field, data field, frame check sequence, <strong>and</strong> a stop<br />
flag.<br />
Frame - (DS1/T1) - A 193-bit entity, consisting of 192 information<br />
bits (24 channels, 8 bits each) plus one framing bit. T-1 frames<br />
occur at the rate of 8000 per second. Twelve frames make a<br />
st<strong>and</strong>ard DS1/D4 format superframe. On modern ESF T-1<br />
facilities, 24 frames are used to make an Extended superframe,
