Data networking components

The data networking components connect the BCM system to the WAN.

WAN interface card

The network interface card (NIC) uses a T1 interface and sync port that connects the BCM system to the WAN. The WAN card is available as a field replaceable unit. For further information on removal, installation, and initialization, refer to “Replacing cards” on page 299.

The international WAN card version (Europe, Middle East, Africa [EMEA]) connects to a channelized T1 TDM circuit with an X.21 or V.35 interface (see Figure 16 on page 47).

The dual V.35 WAN card version connects to channelized T1 TDM circuits using two V.35 interfaces (North America) (see Figure 17 on page 47).

The North American WAN card version connects to a channelized T1 TDM circuit with an integrated T1 DSU/CSU or a V.35 interface, or both (see Figure 18 on page 47).
