Connecting a T1 DSU (or other communications device, I suppose) to a
serial port on a Cisco router with 60-pin serial ports.  Most DSUs with
serial ports that I saw used Winchester connectors (ISO-2593/v.35), but
DSUs with RS-530 ports exist, as well.

Most modern Cisco routers use WICs that have the CSU/DSU built-in, so
you can just cross-connect the smartjack to the RJ48 port on the router.
