MTU 1500 bytes, BW 1984 Kbit, DLY 20000 usec,

reliability 255/255, txload 4/255, rxload 24/255

Encapsulation HDLC, loopback not set

Keepalive set (10 sec)

Last input 00:00:04, output 00:00:00, output hang never

Last clearing of "show interface" counters 37w3d

Input queue: 4/75/453/0 (size/max/drops/flushes); Total output drops: 7190

Queueing strategy: weighted fair

Output queue: 0/1000/64/7112 (size/max total/threshold/drops)

DCD=up DSR=up DTR=up RTS=up CTS=up

I want to understand what is DCD=up DSR=up DTR=up RTS=up CTS=up

then what is DCE...........

& why input errors are there & what is the solution for input errors

DCD = Data Carrier Detect - Set by DCE to imply working link

DSR = Data Set Ready - Set by DCE to imply that the DCE is ready to signal using pins leads

DTR = Data Terminal Ready - Set by the DTE to imply that the DTE is ready to signal using pins leads

RTS = Request To Send - Set by the DTE to tell the DCE that the DTE wants to send data

CTS = Clear To Send - Set by the DCE to tell DTE that the DTE is allowed to send data.
