Connecting Fast Ethernet Channelized E1 Modules to the Network
Connecting Fast Ethernet Channelized E1 Modules to the
Network
In addition to the Fast Ethernet connection (see Figure 5-3), connect one of the following:
• CE1/PRI-B Port on page 5-9
• CE1/PRI-U Port on page 5-11
CE1/PRI-B Port
Use the appropriate cable to connect a CE1/PRI-B (120-ohm) port to an E1 CSU. (See
Figure 5-10, Figure 5-11, and Figure 5-12, showing DB-15, twinax, and RJ-45 CSUs
respectively.)
