Frequently Asked Questions

What is the operating temperature range of the ReadyLinks products?

* CEBxxx: 0° C to 40° C
* IPC14xx: 0° C to 70° C
* RHINO products (OSG, IPC, GTO, GTO-3): -40° C to 80° C

What is the distance limitation of the IP over coax and IP over phone line equipment when using client to client and when using the multiport headend piece?

For both scenarios you are just going to want to operate with no more than 50db of loss in the 5-100Mhz range.  Coax can actually operate at 60db of loss but for practical purposes try to operate below 50db.

For coax this is typically 3,190 ft (RG-59) and 4,000 ft (RG-6).

What are the specifications when it comes to engineering the Coax, splitters, power, etc… for the IPC-1840 and IPC-841 system?

- No more than 50db of attenuation  between nodes at 5-100Mhz

- 1 Master Node (COM Port on 1840C) to up to 8 clients recommended.

- Custom notch filtering between 5-100Mhz available for compatibility with different devices. For example, security cameras.

- Compatible with standard CATV cabling and splitters (RG6, RG59, etc...)

- Compatible with standard RF CATV overlay


Single fiber 802.3ah Gig standard?

Yes, the RHINO platforms as well as the IPC 14xx platforms use SFP's for the optical interface to provide the widest variety of network topologies. SFP's are available to support all the standard fiber interfaces defined in 802.3ah including:

* 100BASE-LX20 – 100Meg dual fiber 20km
* 100BASE-BX20 – 100Meg single fiber 20km
* 1000BASE-LX – 1Gig dual fiber  up to 80km
* 1000BASE-BX20 – 1 Gig single fiber up to 20km
* 1000BASE-PX20 - currently supports 1Gig, and has compatibility with the new 2.5Gbps standard for EPON.i

What is the maximum MTU on a RHINO GTO?

The maximum MTU for the GTO is 1522 bytes plus tags.

HPNA low-band vs. mid-band?

ReadyLinks has HPNA products that support both the 4-20 Mhz and 12-28 Mhz bands, which are commonly referred to low-band and mid-band respectively. This is not a user configurable option but must be specified when ordering the products.

Layer 3 support to Cisco Catalyst?

Currently the RHINO OSG supports layer 2 Ethernet using VLANS for traffic classification and priority. The OSG does contain Layer 3 functions that are used to support the voice protocol stacks. User traffic is currently processed completely in hardware, this makes the RHINO OSG capable of wire speed traffic on the Gigabit WAN ports and all 100 Mbps LAN ports simultaneously.

2 voice ports:  MGCP to G6. SIP to Alcatel/Lucent Softswitch FS5K?

Yes, the RHINO OSG has 2 voice ports. The RHINO OSGs support MGCP and SIP based voice. The ReadyLinks default MGCP implementation is LCS Nuera-style with over 12,000 MGCP enabled RHINOs deployed. We are pursuing discussions with General Bandwidth for MGCP interoperability. Currently SIP interoperability has been tested with CopperCom, MetaSwitch and Tekelec switches. ReadyLinks will test interoperability with SureWest’s G6 MGCP gateway and Alcatel/Lucent Softswitch and make any modifications to achieve interoperability.

10/100 FE ports?

Currently the RHINO OSGs support 4 Ethernet service ports with a 5th Ethernet port over HPNA which supports up to 8 multi-port drops for a total of 12 Ethernet endpoints.

Integrated HPNAv3?

Yes, ReadyLinks is the leading global supplier of HPNA for FTTH optical network terminals.  ReadyLinks supplies HPNA to Calix, Occam, Amino and others. ReadyLinks is a leader in residential HPNA Coax Ethernet Bridges. Both HPNA v3 and HPNA v3.1 are currently available on the OSG. ReadyLinks also has a broad product line of HPNA based products for Residential and Multiple Dwelling Unit implementations. ReadyLinks HPNA is interoperable with several HPNA-enabled IPTV set-top boxes.

TFTP software via DHCP server for upgrades and option id (vendor class identifier)?

Yes, RHINO OSGs support DHCP options for TFTP server for upgrades and configurations.

Option Id – vendor class identifier?

Not currently on the released software, ReadyLinks separates DHCP requests based on VLANs.  For a non-VLAN network, a vendor class identifier could be added.

 

DNS for SIP via DHCP packet?

No, as the Voice service in the RHINO OSG is designed as lifeline POTS service and does not use DNS for SIP via DHCP packet.  Reliability of service is reduced using DNS for SIP calls because of possible unavailability of the DNS server.  The SIP stack in the RHINO OSG supports DNS service and can be configured in the next software release if required.

 

NTP timeserver via DHCP packet?

No, instead the RHINO OSG NTP time server is automatically configured via DHCP configuration file or the CLI.  Configuration via DHCP option field could be added in next release of software if required.

    No, will not see anything.

    For the IPC-1410, IPC and OSG-H, how is hacking prevented when using an HPNA client with a packet sniffer such as Wireshark?

    The RHINO products set a security bit preventing anything from being connected on the network. No visibility to device without the access code. The RHINO products will only allow authorized OUIs to connect. The RHINO products will, in addition, generate an alarm with foreign devices detected on network.
