2.16.7 Recommendation
It is strongly recommended that installers of the router network are familiar with IP
networking, router technology and especially Cisco products.
If such familiarity does not exist, it is strongly recommended to seek advice with a knowledge
Cisco installer.
2.16.8 Recommended router hardware
The router hardware recommended from Damm Cellular Systems A/S is a Cisco 1841
modular router.
This router type has been tested and verified with the TetraFlex
®
multisite system.
According to Cisco specifications – the 1841 router is capable of processing 75.000 pps
(packets per second) – resulting in a theoretical maximum throughput of 38.4 Mbit/s.
If this capacity for some reason should not be sufficient – it may be considered to focus on
the Cisco 2811 router. This offers 120.000 pps/61.44 Mbit/s capacity plus it offers support for
48V power supply.
Other router types and brands may be applicable. But in case the router type is not Cisco –
Damm Cellular Systems A/S will not be able to offer any support.
2.16.9 Recommended router firmware
The recommended firmware for the Cisco 1841 router is
c1841-advsecurityk9-mz.124-15.T1.bin
This has been tested and verified with the TetraFlex
®
multisite system.
Any Cisco 1841 deployment with firmware revision lower than the specified – will not be
supported.
