<< Hi, what's the usual way of doing two phone lines in North American
residences?

1) Using inner and outer pairs of an RJ11 connector?

2) Using inner pairs of two RJ11 connectors?

Or does it vary from place to place etc.?

The US Standard for two lines is a RJ14C "configuration". Physically it is as
you describe.

The RJ11 and RJ14 configurations both use a 6 position miniature modular jack
and plug.

Pins 3 and 4 are line 1 Ring & Tip, respectively.

Pins 2 and 5 are line 2 Tip & Ring, respectively.

I'm fairly certain that Canada uses the same arrangements, but with differently
named configurations.

As to "does it change from place to place?.... It can, because on the customer
side of the NI the customer can do anything they want with jacks, plugs, and
hard-wire. The Standard configurations are *required* only at the NI.
