Routers
The BTS router is a Cisco 1760 1U router. It has two WIC cards installed. One is a dual port T1 card, and
the other is a four-port ethernet switch. The ethernet switch provides a local network for the server, its
iLO, and any other diagnostic computers. The T1 card provides a connection to the BSC site. Some of the
BTS sites are daisy chained together, and use both T1 ports, while some only use one. Ports are labeled:
(slot number of the card)/(port number on the card)
