Page 4: Introduction
INTRODUCTION UCM6XXX series have integrated FXO ports allowing connection of PSTN lines and/or lines from traditional analog PBX. An analog trunk can be defined as a single line or multiple lines (PSTN lines or lines from traditional analog PBX). Each UCM6XXX supports at least 2 FXO ports and reaching 16 FXO ports for UCM6116 model. Using analog trunks allow customers to keep using their actual PSTN lines/PBX lines and integrating them to VoIP systems such as UCM6xxx giving it hybrid capability from VoIP to PSTN and vice versa and taking VoIP and other services offered by UCM6xxx including mobility and reducing calling costs, call recording, IVR,... -
Page 5: Ucm6Xxx Setup Overview
UCM6XXX SETUP OVERVIEW To connect analog lines to UCM6xxx, please follow the below steps: • Connect the UCM6XXX to the Network via WAN/LAN Port, and power it on. • Once the UCM6XXX boots up and connects to the network, the corresponding LAN/WAN LED indicators will be in solid green and the LCD shows the IP address •... -
Page 6: Configuring Analog Trunks
CONFIGURING ANALOG TRUNKS Use a computer connected to the same network as the UCM6XXX, then login to the web GUI of the UCM6XXX by typing the IP address shown on its LCD on your browser, and type in the admin username and password. PBX Status After login, the first default page will show the UCM6XXX status, this will help users to check the FXO Ports status and give the ability to quickly see the FXO overview, without physically monitoring the FXO LEDs. -
Page 7: Create A New Analog Trunk
Create a New Analog Trunk To create a new analog trunk: 1. Go to Web GUI→PBX→Extension/Trunk→Analog Trunks. 2. Click on to add a new analog trunk. Figure 3: Create a New Analog Trunk 3. The following figure will pop up, allowing users to configure the connected analog lines to the FXO port. Figure 4: Analog Trunk Configuration Page Please refer to the following table for Analog Trunk configuration parameters. - Page 8 Table 1: Analog Trunk Configuration Parameters Select the channel where analog trunk is connected (Channel 1, Channel2…) • UCM6202/UCM6102/UCM6510: 2 channels • UCM6204/UCM6104: 4 channels FXO Port • UCM6208/UCM6108: 8 channels Note: Users can select multiple channels if the trunk is using multiple lines. Please refer to [DAHDI Out Line Selection] for more options.
- Page 9 Use CallerID Configure to enable CallerID detection. The default setting is “Yes”. Configures how faxes to this extension will be handled. None: Faxes will not be processed. Fax Mode Fax Gateway: Faxes to this extension will be processed and converted from T.30 to T.38 or vice-versa.

Allows external numbers the option to get directed to the extension that last called Direct Callback them.

Page 11: Create Outbound/Inbound Rules
Default value: f1=480@-50,f2=620@-50,c=250/250 Click on "Detect" to detect the busy tone, Polarity Reversal and Current Disconnect by PSTN. Before the detecting, please make sure there are more than one channel PSTN Detection configured and working properly. If the detection has busy tone, the "Tone Country" option will be set as "Custom". -

Page 13: Create Outbound Routes
In the above example, incoming calls during office hours will be routed to IVR, otherwise calls will be routed to extension 1000(Out Of Office hours). Figure 8: Inbound Routes Created Create Outbound Routes 1. Go to Extension / Trunk→Outbound Routes. 2. -

Figure 10: Outbound Rule Created Once the outbound rule is created, it can be edited anytime by clicking on icon or deleted by clicking on icon. Using Analog Trunk as Failover Failover Trunks are used when the primary trunk fails in order to assure the continuity of external calling service for extensions. -

Page 17: Acim And Pstn Detection
ACIM AND PSTN DETECTION UCM6xxx series support ACIM and PSTN detections modules allowing auto-detection and configuration of PSTN lines, this helps getting best parameters to use on PSTN lines avoiding common issues when it comes to use PSTN lines such echo, noise, calls not ended when remote party ends the call. ACIM Settings Users may sometimes face audio quality issues like noise, echo, audio volume level and choppy voice issues, this is mostly related to impedance parameters not configured correctly on the FXO ports. -
Page 18: Pstn Detection
4. Users can manually enter the ACIM settings by selecting the value from dropdown list for each port. Or users could choose the detect option (either ERL or Pr) then click on "Detect" to automatically detect the ACIM value. The detecting value will be automatically filled into the settings. Figure 14: ACIM Settings 5. -

Figure 23: A key dial-up FXO Note: When using a Key Dial-up FXO feature the outbound trunk for the analog trunk need to have internal permission. As well as it should be the trunk with the highest outbound route priority. Step 2: Import Raw File to an Audio Analyzer Software In this step we will be analyzing the Analog Record Trace using Audacity. -

• Encoding to “Signed 16bit PCM” • Byte order to “No endianness” • Channels to “1 channel (Mono)” • Sample rate to “8000 Hz” Figure 25: Import Raw Data Parameters 3. The result will be similar to the following figure: Figure 26: Raw Data Imported Step 3: Measuring Cadence Once the RX raw file is successfully imported, we can now measure ringing and silence duration that will... -
Page 26: Figure 27: Measuring Cadence
Figure 27: Measuring Cadence The results are 329ms of ringing and 332 of silence, we will round them both to 330, hence the Cadence duration is c=330/330. Step 4: Measuring Busy Tone Frequencies 1. On Audacity tool bar, go to Analyze → Plot Spectrum. 2. -
Page 27: Figure 28: Busy Tone Frequencies
Figure 28: Busy Tone Frequencies In this example we have only one frequency Peak, hence the Busy tone frequencies are f1=436Hz@- 20dB and f2=0Hz@–20dB. (We have rounded the attenuation value to -20dB). P a g e UCM6XXX Analog Trunks Guide... -
Page 28: Monitoring Analog Lines
MONITORING ANALOG LINES The UCM6XXX supports SLA (Shared Line Appearance) that allows mapping the key with LED on a multi-line phone to different external lines. When there is an incoming call and the phone starts to ring, the LED on the key will flash in red and the call can be picked up by pressing this key. -

Page 30: Sample Configuration
Sample Configuration 1. Go to web UI→Extension / Trunk→Analog Trunks page. Create or edit the analog trunk. Make sure “SLA Mode” is enabled for the analog trunk. Once enabled, this analog trunk will be only available for the SLA stations created under web UI→Extension / Trunk→SLA Station page. Figure 32: Enable SLA Mode for Analog Trunk Click on “Save”. -
Page 31: Figure 35: Sla Example - Mpk Configuration
Figure 35: SLA Example - MPK Configuration Now the SLA station is ready to use. The following functions can be achieved by this configuration: • Making an outbound call from the station/extension, using LINE key When the extension is in idle state, pressing the line key for this extension on the phone to off hook. Then dial the station’s extension number, in our example, dial 3000 or 3001 on the configured Phone to hear the dial tone.
