External Connections
This section contains external connection requirements for the Cisco 3600 series.
The Cisco 3620 and Cisco 3640 provide the same electrical interface types and modes; however, the
Cisco 3620 is a two-slot modular access router, while the Cisco 3640 is a four-slot modular access
router. Both routers allow identical LAN and WAN connections that can be configured by means of
interchangeable network modules and WAN interface cards.
The Cisco 3620 and Cisco 3640 have the following external connection requirements, depending on
the interface modules ordered:
• The EIA/TIA-232 console port is configured as DTE and uses an RJ-45 connector
The router ships with a cable kit to connect a console (an ASCII terminal or PC running terminal
emulation software) to the console port. The console cable kit contains an RJ-45-to-RJ-45
rollover cable and RJ-45-to-DB-9 and RJ-45-to-DB-25 female DTE adapters (labeled Terminal).
Synchronous serial interface types, except EIA-530, are available in DTE or DCE format: DTE
with a plug connector at the network end and DCE with a receptacle at the network end. V.35 is
available in either mode with either gender at the network end. EIA-530 is available in DTE only.
