ztcfg -vv
will tell you the number of channels, so you can tell whether
the card is in T1 or E1 mode.

You can use

rmmod wct4xxp
modprobe wct4xxp t1e1override=0xFF
ztcfg -s
ztcfg -vv

to switch all port on the card to E1 or 0x00 to switch to T1.
(*not* permanent)

To do a permanent change you could edit /etc/default/zaptel
(Debian and CentOS) or /etc/sysconfig/zaptel (CentOS).
Look for wct4xxp_ARGS.
