Chapter 2 Overview WinLink™ 1000 System Components WinLink™ 1000 point-to-point solution is made up of a number of key components. Typically, each side of the link comprises an Indoor Unit (IDU), an Outdoor Unit (ODU) and an antenna. A CAT5e cable from the IDU to the ODU provides both Ethernet and Power. The link is managed via the WinLink™ 1000 Manager application.
The Indoor Unit (IDU) The IDU provides TDM and Ethernet ports to connect to the link. It also provides power to the ODU. The IDU is available in four configurations: IDU-E A compact, half 19 inch wide, 1U plastic unit, providing up to two Ethernet ports and up to two E1/T1 interfaces. Figure 2-2: IDU-E Front Panel Figure 2-3: IDU-E Back Panel IDU-C A 19 inch, 1U metal unit, providing two Ethernet ports, 4xE1/T1 interfaces, and dry contact connector alarm.
Figure 2-7: Backup link for E1/T1 connections Power Over Ethernet Units Power over Ethernet units provide Ethernet services only. Power over Ethernet (PoE) An extremely compact device, the Power Over Ethernet (PoE) provides Ethernet only services through one Ethernet port. Figure 2-8: PoE 1. Note: The PoE can only be connected to ODU’s that are PoE enabled, or that are High End or Access ODU’s.
O-PoE Similar to the PoE, with weatherproof casing and sealed connectors that enables outdoor connectivity (a special mounting kit is supplied for attachment to a mast). Figure 2-10: O-PoE Unit The Outdoor Unit (ODU) The ODU is the radio transceiver of the WinLink system and is the main component of the system. The ODU connects to an antenna that enables radio communication and can be mounted on a pole or wall. The ODU connects to the IDU via a CAT5e cable.
Figure 2-12: Typically used External Antennas There are three series of ODU: • WinLink™ 1000 Access • WinLink™ 1000 • WinLink™ 1000 High End The following table shows the differences between the systems: Table 2-1:ODU Series Typical Characteristics WinLink™ 1000 Access WinLink™ 1000 WinLink™ 1000 High End Max Ethernet Throughput 2Mbps 18Mbps 18Mbps Max.
WinLink™ 1000 Manager The WinLink™ 1000 Manager is an SNMP based element and link management application which manages a complete link via a single IP address. It identifies the IP Address, Subnet Mask, and Trap Destination for each Site and also monitors the Radio Interface – RSS [dBm] and Ethernet Service – Rx Rate and Tx Rate. The Manager software facilitates the Link installation and Link configuration between the ODU units.
(All Indoor Unit) AIND The AIND - All Indoor unit offers a single enclosure for Radio and Multiplexer modules. It enables outdoor placement of only a passive element. Figure 2-14: AIND - "All Indoor" unit connected to antenna WinLink User and Installation Guide Version 1.
