PA-A2 ATM CES Cables, Connectors, and Pinouts
Cables on the ATM CES port adapter fall into two categories described in the following sections:
•
•
ATM CES port adapter interfaces are full-duplex. You must use the appropriate ATM interface cable
and CBR cable to connect the ATM CES port adapter with an external ATM network. The ATM CES
port adapters, shown in
transmitting and receiving data at rates of up to 155 Mbps bidirectionally for OC-3, 44.736 Mbps
bidirectionally for DS3 over T3, and 34 Mbps bidirectionally for E3.
ATM Port Cables
Two types of cables are available for use with the ATM CES port adapter's OC-3 and T3/E3 ATM ports:
•
•
Both ATM cables conform to the EIA/TIA-612 and EIA/TIA-613 specifications. The ATM port on the
ATM CES port adapter is a DTE device.
For OC-3 single-mode, the ATM CES port adapter connects to the SONET/SDH 155-Mbps single-mode
optical fiber physical layer, either STS-3C or STM-1. The connection is made by means of single-mode
OC-3 ATM cables with SC connectors (see
shipped with removable dust covers on each SC connector. Keep covers on any connectors that are not
being used.
