The systems support both analog outside lines and ISDN lines and can be configured as ISDN only, analog only, or a combination of the two. The initial TD-824i system provides capacity for up to 4 outside lines and 8 telephone sets. The system may be expanded to a maximum of 8 lines and 24 telephones. The TransTel TD Series offers the smaller customer using the TD-824i system the ability to expand and migrate into the TD-1648i.
