The Case Communications 6540M MIL Spec Rugged Router Switch



The  6540 MIL Spec Rugged Router Switch , supports ADSL 2+ (G.992.5) for use on existing networks,. ADSL 2+ provides a downline rate of 24Mbps and  standard upstream rate of 1.4Mbps. An upstream rate of 3.3Mbps can be achieved using Annex M.


The Case Communications 6540 MIL Spec Router  supports V.DSL2 (Very-high-bit-rate digital subscriber line 2) ( also known by British Telecomm as (FTTC) Fibre to the Cabinet) ( G.993.2). VDSL2 has an upstream data rate of 20 Mbps and a down-link data rate up to 80 Mbps.

Dual Gigabit ports

The 6540M-  Rugged Router  is supplied with dual 100/1000Mbps ports, which can be fitted with dual Fibre via SFP Ports

Power Over Ethernet Ports

Because 6540M is equipped with 4 x 10/100Mbps PoE / PoE+ ports, this makes the 6540M ideal for high bandwidth applications such as IP Telephony,  IPTV,  CCTV and monitoring in real time as well as Industrial Applications. Input voltage to provide PoE is between 23vdc and 55vdc.

The 6540M MIL Spec Rugged Router Switch has been designed to operate reliably in harsh conditions

The  Case Communications 6540M Industrial Router has been designed from the ground up to operate reliably for mission critical applications in harsh conditions without the use of fans. The 6540 is supplied as both a DIN Rail and, Rack mounted router, and with power and all input / output on the front panel consequently, making support easy.

The 6540M SNMP Management with last gasp

The 6540M Industrial V.DSL / ADSL / Fibre router  is equipped with a last gasp facility allowing it send out an SNMP (Simple Network Management Protocol )  Trap in the event of a power failure.

Ethernet Switch

The internal Ethernet switch with in the 6540M provides 4 x 10/100Mbps ports and two 10/100/1000Mbps Mini GBIC Ports. These can provide the option of two Gigabit Fibre ports if required. Furthermore the 6540M also has the ability to provide PoE / PoE+ to attached devices such as IP Phones,  Pan and Tilt CCTV etc.


The Case Communications 6540M has high levels of security supporting tunnelling protocols such as IP Sec and GRE Tunnelling. Encryption options include AES, and 3DES .  The 6540M has the ability to use the SHA 2 encryption algorithms The SHA-2 family consists of six hash functions with digests (hash values) that are 224, 256, 384 or 512 bits: SHA-224, SHA 256, SHA-384, SHA-512, SHA 512/224,SHA0512 / 256 . Furthermore  VLAN Tagging is supported, allowing VLAN Tags to be taken over the network to a remote subnet.


The 6540M Industrial Router is managed locally or remotely via a Browser, SNMP V1/V2/V3 or via a Command Line Interface (CLI).


The 6540M supports Multicast using PIM SM making the 6540M ideal for IP TV and CCTV Broadcast networks. Consequently as an Industrial router with Multicast support the 6540 is  ideal for CCTV and security networks.
