System Availability: All systems
The MIPU / LIPU and GIPU / GIPH IP interface card works in conjunction with the system processor to provide distributed IP processing capabilities that include peer-to-peer IP telephone
communication and IP Strata Net multi-system networking. MIPU / LIPU and GIPU / GIPH cards install in card slots in Strata CIX base or expansion cabinets.
The MIPU comes in two flavors: MIPU16 and MIPU24. The MIPU supports up to 24 channels
even when the echo tail length canceller is set up to 64ms. The GIPU / GIPH installs into the Strata CIX40 system. The GIPU / GIPH card on the CIX40 supports up to 8 IP channels. The LIPU card can support up to 16 IP channels on all CIX systems. With the LIPS sub-card on board it can support up to 32 channels. Each IP card type has a Network Interface Card (NIC).
When programmed for G.7 11 codec, or G.729A with 16 ms echo cancel delay the MIPU, LIPU or LIPS supports 16 IP channels and GIPU / GIPH supports 8 IP channels. When programmed for G.729A codec and 32 ms echo cancel delay the LIPU or LIPS provides 12 of the 16 channels; on GIPU / GIPH 6 of 8 channels are available. Refer to the Strata CIX Programming manual for more details.
The MIPU / LIPU / LIPS / GIPU and GIPH supports all “IP” functionality in the Strata CIX. This includes the following:
| • | Multiple protocols supported: |
| • | MEGACO+ delivers a consistent user interface over all Toshiba IP endpoint devices, except SIP telephones. Toshiba has enabled the MEGACO protocol for call control to provide more stimulus/response capabilities that allows all the feature functionality of digital desktop telephones to be supported on IP telephones. The MEGACO+ protocol is able to implement this feature functionality consistency much better than could be done using other VoIP protocols. |
| • | SIP (Session Initiation Protocol) telephones provides basic functionality that can be used for very basic user capabilities. Toshiba supports only the Uniden telephone that Toshiba has approved for interoperability. |
| • | SIP Trunking is an application layer protocol used for establishing sessions in an IP network. SIP Trunking allows the CIX to get PRI like services from an Internet Telephony Service Provider using SIP. |
| • | MIPU / LIPU/LIPS and GIPU / GIPH IP endpoint devices and interfaces (requires IP Endpoint license): |
| • | SoftIPT on PDA, Notebook and TabletPC’s |
| • | Strata Media Application Server (MAS) |
| • | MIPU / LIPU/LIPS Port devices and interfaces (requires Basic Port license on all CIX systems, except with GIPU / GIPH because all Basic Ports are fully licensed on CIX40). |
| • | MAS ACD Announcement Ports |
| • | StrataNet IP Network resources |
| • | In addition to the above features, the MIPU also includes the following: |
| • | Backward compatibility with LIPU |
| • | Compatible in the CIX40, CIX100, 200, and 670 The MIPU1 6 is compatible with the CIX40 with CIX Release 5.1 software. |
| • | Log files collected remotely from the MIPU |
| • | MIPU card uses one IP address |
| • | Tail-length echo cancellation increased from 32 ms to 64 ms (G.7 11 and G.729A) |
| • | Quality of Service (QoS) threshold alarm notification and measurement |
| • | Connects between a node using G.711 A-Law codecs and a node using G.711 Mu-Law codecs. |
| • | The maximum transmission interval of voice packet at using G.7 11 codec is 40ms (80ms in LIPU) |
| • | RTP ports used by IPTs can be user modified |
| • | Continuous rebooting (even after six failed attempts) |
| • | For a comparison of the MIPU and the LIPU refer to Table 25. |
Miscellaneous
| • | The MIPU / LIPU / GIPU / GIPH supports both G.7 11 and G.729A standard codec compressions simultaneously. The type of compression used is set independently for each telephone in system programming. |
| • | With the MIPU / LIPU/ GIPU / GIPH, the IP telephone works with DSL and cable routers. |
The MIPU / LIPU / GIPU / GIPH operates on the network at 100 Mbps and can be connected to
a fast switch router, LAN, WAN, etc. When connecting remote IP telephones to the MIPU / LIPU / LIPS and GIPU / GIPH over the Internet, a VPN router is needed to circumvent Network Address Translation (NAT) and firewall issues by tunneling.
| • | MIPU / LIPU / GIPU / GIPH provides MEGACO+ mobility to enable roaming. The LIPU / LIPS and GIPU / GIPH enables remote IP telephones to be connected over VPN and non-VPN IP networks. |
| • | MIPU / LIPU / GIPU / GIPH firmware can be updated locally or remotely using eManager. This enables service personnel to update IP equipment with new features and enhancements as they become available. Updates require a brief interruption of IP telephone operation (a few minutes). |
