Lines problem

I have a 14.4k leased line which I use to connect the central office with my remote site. I have used Codex Modems on both sides and Cisco 2611 and 1601 routers on the central and remote sites respectively. The line has been losing a lot of packets hence inefficient for my purpose. The Telcom company says its my fault but i don't believe them because the configuration on the routers and modems are similar to the rest of my routes and modems and the R232(60,15) cables have been properly tested. Below are the interface statistics of the serial line of the central site router:

Serial1/3 is up, line protocol is up

Hardware is CD2430 in sync mode

Description:

Internet address is 192.168.40.6/24

MTU 1500 bytes, BW 128 Kbit, DLY 20000 usec, rely 130/255, load 1/255

Encapsulation HDLC, loopback not set, keepalive set (10 sec)

Last input 00:00:03, output 00:00:00, output hang 2d06h

Last clearing of "show interface" counters never

Input queue: 0/75/0 (size/max/drops); Total output drops: 656

Queueing strategy: weighted fair

Output queue: 0/1000/64/649 (size/max total/threshold/drops)

Conversations 0/41/256 (active/max active/max total)

Reserved Conversations 0/0 (allocated/max allocated)

5 minute input rate 0 bits/sec, 0 packets/sec

5 minute output rate 0 bits/sec, 0 packets/sec

158266 packets input, 8775562 bytes, 0 no buffer

Received 107449 broadcasts, 0 runts, 3 giants, 0 throttles

5683310 input errors, 3263774 CRC, 0 frame, 0 overrun, 0 ignored, 2419503 abort

248544 packets output, 45704953 bytes, 0 underruns

0 output errors, 0 collisions, 56701 interface resets

0 output buffer failures, 0 output buffers swapped out

89 carrier transitions

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

What could be causing such a problem?
