Nightingale XB14-750 Series Documentation

NB: Nightingale XB14m-750 Series User Guide is in the PDF attached to this note.



Q. Which version of Nightingale is most appropriate for our needs?

A. Generally the M-series Nightingales are best suited to complex network topologies, and where WAN-side DHCP is not available (or where the WAN-side IP may be dynamic or quasi-static). Non-M series Nightingales are intended for straight-through network setups where WAN-side IP is available via DHCP (for example, regular cable or DSL).

Q. Which IP protocols will pass un-molested through the Nightingale?

A. The Nightingale functions like an Ethernet switch (it is a layer 2 device); consequently all IP protocols pass through the Nightingale (as they would through an Ethernet switch).

Q. Does Nightingale affect VPN tunnelling, multiple WAN-side IPs, file services, network services, DMZ configurations, etc.?

A. No. As explained above, all this traffic will pass-through unaffected.

Q. Does Nightingale set aside bandwidth for voice?

A. Yes. Voice consumes about 24kbps-40kbps per channel. So 10 simultaneous calls will utilize about 400kbps of bandwidth. Nightingale is configured to set as much bandwidth aside as your voice requirements dictate on an as-needed basis.

Q. Are there any special setup requirements?

A. Yes. There must be no parasitic paths around the Nightingale; in other words, all Internet traffic must flow through the Nightingale. We also recommend a network stress-test before and after installing the Nightingale to confirm that the installation is functioning correctly. The stress-test is non-invasive, does not require downtime and usually takes less than 10 minutes. Stress testing is documented here.
