Last reviewed: October 6, 1997

Article ID: Q173859

The information in this article applies to:


 * The Microsoft Network versions 2.0, 2.5

SYMPTOMS
When you connect to MSN, The Microsoft Network, with a U.S. Robotics Courier I-Modem, you may not connect with dual-channel access.

CAUSE
This behavior can occur because the U.S. Robotics Courier I-Modem is a single-channel Integrated Services Digital Network (ISDN) access device.

RESOLUTION
To resolve this issue, contact U.S. Robotics to obtain their ISDN software version 2.06 (or later if available).
