The PathBuilder switch is available with five different serial WAN interface
options:
The model S580 PathBuilder switch has eight high-speed
multifunction Flex-WAN serial connectors that provide connection to
industry-standard V.35, RS-232, RS-449, RS-530, or X.21 Data
Communications Equipment (DCE) or Data Terminal Equipment (DTE)
serial devices. You can buy Flex-WAN cables separately from 3Com.
See "Flex-WAN Serial Connectors and Serial Cables" on page 90 for
more information about the Flex-WAN cables.
The model S593 and S595 PathBuilder switches have two T3/E3 WAN
interfaces. Each interface can be connected to either an external
CSU/DSU via an HSSI connector, or directly to a T3/E3 line via a BNC
connector.
The model S590 PathBuilder switch has four high-speed multifuntion
Flex-WAN serial interfaces and four Ultra-WAN CSU/DSU interfaces
supporting PRI, channelized, and unstructured connectivity on a per
connector basis at T1 and E1 line rates.
The model S598 and S599 PathBuilder switches have eight or four
high-speed multifuntion Ultra-WAN CSU/DSU interfaces supporting
PRI, channelized, and unstructured connectivity on a per connector
basis at T1 and E1 line rates.
The model S574 and model S578 PathBuilder switches have two interface
modules, each with an OC3 UNI connector supporting two types of
optical fiber cables; single-mode and multi-mode, and one set of transmit
(Tx) and receive (Rx) coaxial connectors. Only one interface type will be
active on each module.
WARNING: Optical Safety. Under normal viewing conditions there is no
hazard from the Transmit LED. It is recommended however that the LED is
not viewed through any magnifying device while it is powered on. It is
advisable that the fiber TX port and fiber cable ends are never viewed
directly when powered on.
