IBM 8265: Product Description
WAN 2 Module
The WAN 2 module (Feature Code 5602) enables direct communication between
ATM networks, residing in different locations, over the Wide Area Network (WAN).
The module is a single-slot module that can host any two daughter cards of the
following types:
•
4-port E1/T1, with DB15 connectors for E1 over coaxial cable at 2Mbps, RJ-48
connectors for E1/T1 over twisted pair cable at 2Mbps (E1) or 1.5Mbps (T1)
•
1-port E3, with BNC connector, over a coaxial cable at 34Mbps
•
1-port DS3, with BNC connector, over a coaxial cable at 45Mbps
•
1-port STM-1, with SC connector, over a multimode fiber cable at 155Mbps
•
1-port STM-1, with SC connector, over a singlemode fiber cable at 155Mbps
•
1-port OC3, with SC connector, over a multimode fiber cable at 155Mbps
•
1-port OC3, with SC connector, over a singlemode fiber cable at 155Mbps.
The module supports the UNI, IISP, and PNNI interfaces. The STM-1 interface
implements full SDH support, while the OC3 interface implements SONET support.
The UTOPIA interface connects the daughter cards to the motherboard in the
following way:
•
ATM data cells are transferred via UTOPIA
•
Daughter cards access the ATM functions via UTOPIA
Up to four modules can be used in the 8265 (slots 1, 3, 5, and 7).
