V.35 Speed and Distance Limitations
The table here lists the different V.35 speed and distance limitations:
Caution: The EIA,TIA-449 and V.35 interfaces support data rates up to 2.048
Mbps. Cisco advices not to exceed this maximum as it could result in loss of
data.
| Data Rate (Baud) | Distance (Feet) | Distance (Meters) |
|---|---|---|
| 2400 | 4,100 | 1,250 |
| 4800 | 2,050 | 625 |
| 9600 | 1,025 | 312 |
| 19200 | 513 | 156 |
| 38400 | 256 | 78 |
| 56000 | 102 | 31 |
| T1 | 50 | 15 |
CAB-V35MT Serial Cable Assembly
The cable gender for this product (part number 72-0791-01) is male DB-60 to male Winchester 15 Pin, mode - DTE.
The CAB-V35MT serial cable is used in the Cisco 7000 family, Cisco 4000 series, Cisco 3600 series, Cisco 2500 series, Cisco 1600 series, Cisco access servers, and AccessPro PC cards. This cable has a male DB-60 connector on the Cisco end and a male Winchester connector on the network end.
