NEC 2000 IPS manual Options Per Location

Chapter 13 Voice Over IP (VoIP)

12. Following parameters can be assigned on a Location basis. The Location is a kind of group (similar to Tenant in a PBX) that is defined for bandwidth management and parameter settings for LAN traffic based on the location of IP terminals. Maximum 64 Location numbers can be assigned per system.

Options Per Location

Type of Codec selection list	DiffServ	Operation when over usable
Type of Service (ToS)	Setting Area/Country	bandwidth threshold.
PAD control pattern	IP-PAD Group number	Jitter buffer
Echo canceller-ON/OFF	Usable Bandwidth

13. When the IP adapter unit is attached with a Dterm Series E/Series i terminal, other optional adapters (except for AD/DC adapter unit) cannot be attached with the Dterm Series E/Series i terminal.

14. Dynamic Host Configuration Protocol (DHCP) cannot be used to assign an IP address to an MP.

15. Login is restricted in following conditions.

When designating a non-existent station number. ("Unregistered" is displayed on the LCD.)

When designating a station number that is not assigned to Multiline Terminal. ("Illegal LEN" is displayed on the LCD.)

16.Logout should be allowed by a station class of service. If not allowed, reorder tone will be heard and "Restrict" will be displayed on the LCD.

17.Intranet to support Quality of Service (QoS) is preferable to connect IP Stations, to reduce the delay of connection and voice, and the inferior grade of voice quality.

18.IP Stations operate on 10 Mbps or 100 Mbps LAN based on IEEE 802. (100Mbps LAN is recommended.)

19.IP Stations support Dynamic Host Configuration Protocol (DHCP). (External DHCP server is required.)

20.Network-based DRS (external DRS) 3.0 is not supported.

21.Switching hub(s) are required.

22.Spanning Tree (IEEE 802.1d) function is not available.

23.LACP (Link Aggregation Control Protocol, IEEE 802.3ad) function is not available.

24.The UNIVERGE NEAX 2000 IPS can configure the speed mode of the LAN interface for MP/IP-PAD card, in addition to Auto Negotiation (default).

The speed mode for the MP card can be set to 100 Mbps full duplex in system data programming. System initialization is required for the mode to take effect.

The speed mode for the 32IPLA/32IPLA-A card can be set to 100 Mbps full duplex, 100 Mbps half duplex, or 10 Mbps half duplex, using the rotary switch on the card. The card initialization is required for the mode to take effect.

The speed mode for the 8IPLA card can be set to 100 Mbps full duplex using the DIP switch on the card. The card initialization is required for the mode to take effect.

25.When the QoS Display function key is pressed on IP Enabled Dterm, the QoS information (number of lost packets, codec type and payload size) is displayed.

A function key on IP Enabled Dterm should be assigned as QoS Display key in system data programming.

No other LCD information from PBX such as Clock/Calendar, calling station number and name is displayed during QoS display.

To stop QoS display, press the EXIT soft key (not EXIT button). Even if the call ends and the Dterm user goes on-hook, the QoS display remains unless pressing the EXIT soft key.
