2 Product Overview AMT-Series Indoor Unit Outdoor Unit L-Series Indoor Unit

3 Point-to-Point Radio Platform 7..8 GHz 11 GHz 13 GHz 15 GHz 18 GHz 23 GHz 38 GHz Independent TX and RX oscillators allow any T/R spacing Coverage for all standard frequency bands

4 What makes Proteus AMT different? Total capacity 122 Mb/s Efficient use of Bandwidth Flexibility Combined Ethernet and PDH in the same radio

Data Rate Independent Outdoor Unit

–AMT version IDU (up to 122 Mb/s) : Replaceable IF card and LIMs Bandwidth, Throughput, Customer Interfaces (Defined by IDU) L-series IDU (up to 50 Mb/s) : Software configurable BW, no LIMs

7 L-Series IDU L-Series IDU Total Capacity: 50 Mb/s

8 Proteus AMT L-Series Software Configurable Common hardware for all available capacity, bandwidth, modulation, application All upgrades by software keys –Channel bandwidth: 3.5, 7, 14 or 28 MHz –Ethernet: mixed transport “on” or “off” –High Throughput (8PSK) or High Gain (QPSK) –PDH: 2, 4, 8, 12 and 16 x E1 –100BaseT Ethernet to 50 Mbps –Mixed transport of N x E1 plus Ethernet in the same radio

Type-N IDU/ODU Cable Connection DC Power Input Power, Major & Minor Alarm LEDs Laptop Serial Connection (9-pin D) HSB Signaling for use with protection shelf DB-78 E1 Tributary Input/Output Connector Cast aluminum chassis is convection cooled, no fans SNMP Network Management (10BaseT - RJ- 45) 10/100 BaseT Ethernet RJ-45 (2, bridged) Proteus AMT L-Series IDU

10 AMT-Series IDU AMT-Series IDU Total Capacity: 122 Mb/s

11 Plug and Play with Bandwidth, Modulation, and Data Speed 4 Types of LIMs (Field Replacable) 4 Bandwidths (Field Replacable) 4 Types of Modulations (SW) Scalable LIM capacity (SW) Easy expansion to higher capacities even within the same bandwidth (SW) LIMs are “hot swappable”, without stopping existing traffic Large variation of different possibilities

The AMT Series IDU: automatically identifies the installed IF bandwidth, the installed LIMs and the number of activated E1’s … and adjusts the modulation from QPSK to 32 QAM to remain within bandwidth. (can be changed by the customer to optimize performanc e) Efficient use of Bandwidth

13 Line Interface Modules (LIM) Hot-Swap Automatic Detection Software Configurable Any combination of 2 LIMs can be installed together in an IDU

14

16 Mix and Match E1 and Ethernet Channels Start with all E1s Integrate Ethernet in the same radio Distribute traffic speed between E1s and Ethernet Two ways of extending Ethernet speed –reduce PDH capacity within your existing bandwidth or –use a wider RF band Total radio capacity: 122 Mb/s (100Mb/s + 4E1) Gradual Migration from PDH E1 Platform to IP Telephony

20 Integrated Outdoor Unit - ODU Covers all data rates Reduced logistics, spare parts and product stocking Small, light weight and aesthetic - easily blends into the local environment ODU can be replaced without effecting antenna alignment

21 Proteus AMT - Summary L-Series IDU: 50% higher throughput than “traditional“ MW radios 16 E1 in 14 MHz BW Mix Ethernet and PDH in one system AMT-Series IDU: Up to 3x throughput than “traditional“ MW radios 24E1 in 14 MHz Bandwidth (traditionally: 8E1) 32E1 in one 28 MHz Channel (traditionally 16E1) Mix Ethernet and PDH in one system (add PDH or Ethernet to existing platform) 100BaseT with full 100 Mbit/s in 28 MHz

22 Proteus AMT - Summary Flexibility Change modulation and data rate to stay within licensed bandwidth. Add Ethernet to existing PDH radio Reallocate bandwidth from PDH to Ethernet, or vice-versa
