Frequently Asked Questions
Single fiber 802.3ah Gig standard?
Yes, the RHINO OSG uses SFPs for the optical interface to provide the widest variety of network topologies. SFPS 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.
Important note: upgrading the WAN speed from 100Meg to 1Gig on the RHINO OSG is accomplished via a simple SFP change at the home. The RHINO OSG electronics remain unchanged.
Hardened to 65C?
Yes, all RHINO OSGs support full industrial temperature range -40° to +65°C plus solar load (or +85°C without solar load)
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.
Support IGMP snooping (and/or proxy), and fast leave?
Yes, IGMP snooping is supported on the RHINO OSG. The newest version of OSG software currently in test adds this to IGMP proxy.
LED’s for status and activity verification?

12Volt DC for UPS battery backup?
Yes, in addition supports all alarms via syslog and SNMP for standard UPS model – CyberPower and Alpha. Connections supported are: 12VDC power, 12VDC return, Signal Return, AC Power fail on UPS, Replace UPS Battery, Batter Missing, Low Battery.
Remote management via (ssh, telnet, GUI, etc.)?
Yes, RHINO OSGs support management via telnet on the management VLAN, ReadyView EMS and SNMP for telemetry. GUI and ssh could be added in a future release.
Basic layer 2 switch (supports 1 flat untagged vlan)?
Optional sw available. Normally the OSG supports VLAN separated classes of traffic (Voice, Data, Video, Management). The software load should be complete within the month.
Auto MDIX (10/100 & full/half) and the ability to manually set speed & duplex?
Yes, all service ports support rate and mode negotiation as well as auto cross over. Ports can be provisioned in a fixed mode. Also all Ethernet service ports support cable testing that will report cable opens, shorts, pair crossing and the cable distance from the OSG to the short or open.
Support 100 Mbps none blocking on all LAN ports?
Yes, all RHINO OSGs support wire speed data transfer on all data ports.
Support 1 Gig throughput on WAN port?
Yes, all RHINO OSGs support wire speed data transfer on all data ports.
WAN interface is SFP (1310 TX, 1490 RX)?
Yes, the OSG GigE WAN optical interfaces are SFPs. ReadyLinks stocks SFPs for single fiber and dual fiber configurations for distances from 1km to 80km please see the ReadyLinks catalog list for SFP distance and wavelengths supported.
Ring voltage 85-90volts?
Yes
Minimum 5 REN (Ringing Equivalence Number)?
Yes, extensive compatibility with various POTS appliances has been conducted in different configurations. With over 12,000+ units deployed both the hardware and software has been refined to support both legacy and current POTS appliances.
FAX support (T38 and g.711)?
G.711 fax (T.30) is supported. T.38 is not currently supported.

Yes, extensive compatibility with various POTS appliances has been conducted in different configurations. With over 12,000+ units deployed both the hardware and software has been refined to support both legacy and current POTS appliances. Standard regression testing verifies modem in excess multiple days.
IGMP support for layer 2 bridged networks (ie: HPNA)?
Yes, current software supports IGMP snooping, new software release currently in test upgrades this to IGMP proxy.
