This worksheet describes the telephony requirements for Europe.


Task Description Complete

Access ports

Number of access ports (user licenses) your company purchased: #_____________

 

Telephony setup

How Cisco Unified MeetingPlace will attach to the phone network:

  • Directly to PSTN
  • Through a PBX
 

E1 lines

Order E1 lines to accommodate the number of E1 ports purchased.

 

Trunking type

The trunking type provided with the Cisco Unified MeetingPlace system: Digital trunks

 

PBX requirements

Order additional hardware or software for your PBX to accommodate new E1 lines.


The following telephony components or services can take from 4 to 6 weeks to order and install:

  • Network Telco Service (trunk lines, main phone number, or combined access numbers)
  • PBX specific hardware or software (Smart Blades, software upgrade)
  • Additional hardware (CSU, UPS)
 

Cisco Unified MeetingPlace phone number(s)

The main phone number (800 and/or local) at the beginning of the range.

 

Digital line requirements

  • Standard E1
  • Channelized into 30 channels (30 B channels, plus 1 D-channel and 1 framing channel
  • Ability to receive calls
  • Ability to place calls (required for outdials and alarm outcalls)
  • Ability to hunt all ports (linear, circular, UCD, or ACD)
  • Toll restriction on ports lifted (required for outdials and alarm outcalls)
  • DTMF generated by all PBX or network phones, including the operator console
  • Male RJ-48C jack connector (on the Cisco Unified MeetingPlace side)
 

Numbering plan


If using DID Meeting Access, numbering plan for DID/DNIS or DDI, including ranges for Combined, Profile, and Direct Meeting Access

 

Signaling

One of the following:

  • Euro-ISDN (default configuration)
  • QSIG: either QSIG_ECMA (channels are numbered 1-30) or QSIG_ETSI (channels are numbered 1-15, 17-31)
 

Coding format

One of the following:

  • HDB3 (strongly recommended)
  • AMI

Note: If AMI is used, the number of zeros (0) in a row may exceed the recommended Telco value of 15. This can happen if all participants in the same meeting are on the same span. In that case, a 0s pattern can be sent to all channels at the same time, exceeding the maximum. This, in turn, can lead to meeting participants being dropped by the Telco from the meeting. Therefore, use B8ZS or Jammed Bit, if possible.

 

Framing

One of the following:

  • CRC4 checking (strongly recommended)
  • Non-CRC4
 

Additional hardware

No channel service unit (CSU) required in Europe, because the Telco provides its own.

 

Modem requirements

  • Analog phone line, or PBX connection
  • Pilot number, accessible from outside
  • RJ-11C connector
 

Translation table

Translation table requirements for dialing restrictions.
