ISDN要特殊线缆，医院不会为一个投行小兵去专门布线我都怀疑当时新电信有提供ADSL拨号。可能是她在吹嘘自己。
也有电话转线，就是在配线架上直接跳线，
和电话比，不需要拨号，不会断。也是用modem连接。所以产房最可能就是用电话线拨号。当然也可能笔记本-WiFi-路由器，由路由器拨号上网。
说个题外话，这些年通信技术发展很快啊。
Singtel's ADSL service was subsequently rolled out on a nationwide scale in August 2000.
The first version of the 802.11 protocol was released in 1997, and provided up to 2 Mbit/s link speeds. This was updated in 1999 with 802.11b to permit 11 Mbit/s link speeds. In 1999, the Wi-Fi Alliance formed as a trade association to hold the Wi-Fi trademark under which most IEEE 802.11 products are sold.
