The installation of your TA+P2I is done in a few simple steps:
• Connect the power supply to the TA+P2I and mains: The green LED “READY” at
the front panel will be lit.
Attention: Please use only the delivered power supply!
• Connect „LINE 1“ with the first analogue line of the cable modem, LINE 2 with
the second one. The corresponding LEDs LINE1 and LINE2 will be lit green.
• Connect the ISDN phone(s) to one or both ISDN plugs. As an alternative you
can connect the previous installed ISDN cabling to one of the ISDN plugs.
Note: The ISDN terminating resistors for the ISDN network are integrated
inside the TA+P2I already.
• Check whether you can receive calls using all called numbers. If you have
problems please proceed as follows:
o If one ISDN phone shall react on all incoming calls from both lines it is
necessary to delete all still activated MSN settings inside the ISDN
phone.
o If one ISDN phone shall react only to the phone numbers of one of the
analogue lines of the cable modem, change the former MSN settings and
use the digit “1” as MSN for that phone, which shall react on incoming
call from line 1. Please handle the same way for the ISDN phone that
shall be allocated to line 2, this phone needs the digit “2” as MSN setting.
o Example:
For line 1 was associated the call number 123123123 and for line
2 the call number 456456456
If an ISDN phone shall only accept incoming calls for the number
123123123, set up the MSN of this phone to „1“.
If another phone shall react on incoming calls to 456456456,. set
up the MSN of this phone to „2“.
If a third phone shall react on all incoming calls, so delete all
MSNs of that phone.
• More information you can find in your phone manual. If you have problems
setting up MSNs please contact your dealer or the manufacturer of the phone.
More setups you will find in the next chapter.

3 Usage of the TA+P2I
By adapting with the TA+P2I you can use many supplementary services known from
the ISDN also via the analogue lines, the services have to be activated on the
analogue lines.
The TA+P2I supports the following supplementary services:
• Outgoing call including transmission of calling party number
• Calling line identification restriction
• Incoming call including display of calling party
• Call waiting
• Call hold
• Three party conference (3PTY)
• Barring incoming calls
• Terminal portability (TP)
• Call forwarding (CFU, CFB, CFNR)
More services may be available depending on the characteristics of the analogue
lines, these can be driven from the ISDN phone transparently by key inputs.

3.1 Incoming call
An incoming call will be shown via the ringing tone and the calling number display as
if the ISDN phone would be connected to the ISDN network directly.
To route the incoming calls to the addressed ISDN phones it is necessary to set up
the MSN of each ISDN phone. If the MSN is not configured (MSN = <empty>) in the
ISDN phone, the ISDN phone is ringing on incoming calls both on analogue line 1
and analogue line 2.
If a wrong MSN (a MSN which does not match with any MSN configured in the
TA+P2I) is configured in the ISDN phone, the ISDN phone is not ringing.
By factory the associated MSNs for the two analogue line are set to 1 (line1) and 2
(line2). For using the factory setting set up the MSN of your phones accordingly:
Phone with MSN = 1 is ringing on incoming calls on analogue line 1.
Phone with MSN = 2 is ringing on incoming calls on analogue line 2.
For experts only:
If a phone number according to the call number of the analogue lines shall be used,
you have to set up this correct MSN both in the TA+P2I and the ISDN phones.
To change the setting for the MSN for analogue line 1 please do the following:
• Please enter the following number in on hook state of the ISDN phone
• 00000101xxx = Set the first MSN for analogue line 1 to xxx
(factory default 1: „Dialing 000001011“)
• Go off hook
• Go on hook
Please proceed adequate for the second analogue line, please dial instead:
00000102xxx = Set the first MSN for analogue line 2 to xxx (factory default 2:
„Dialing 000001022“).
Two additional MSNs can be programmed for each line accordingly by using other
dial codes (see chapter configuration).
Note: The settings can only be changed by using an ISDN phone directly
connected to the TA+P2I. Changing the settings via a ISDN PABX are not
possible, because the configuration command is not transmitted to the TA+P2I.

3.2 Outgoing call
An outgoing call will be started identical as if the ISDN phone would be connected
directly to the ISDN network via the menu and the keys of the ISDN phone.
The MSNs entered in the ISDN phone and the TA+P2I define the analogue interface
(line 1 or line 2), that will be used for the outgoing call. If no MSN is defined in the
ISDN phone, the TA+P2I uses the next free analogue line (line 1 or line 2). If a
wrong MSN (a MSN which does not match with any MSN configured in the TA+P2I)
is configured in the ISDN phone, an outgoing call is not possible.
In case that during an outgoing call an assumed call pause of approx. 10 seconds
occur, this can be reduced to approx. 5 seconds by terminating the call attempt with
the # key.
Background: The assumed call pause is caused by the analogue interface (DTMF
tones are not hearable via ISDN) and the cable modem. The cable modem
establishes the voice connection via VoIP.
An example of an outgoing call attempt using the # key looks like follows:
<phone number># (i.e. 123456789#)
Important: Some ISDN phones do not support (or it is disabled by default) dialing
using # key in the dial string. Please refer to the user manual of your ISDN phone
to change this setting.
To make an outgoing call with calling line restriction please use the menu user
interface of the ISDN phone. The signaling sequence will be adapted automatically
by the TA+P2I.
Note: The ISDN phone can display „connected“ although the connection has not
been established completely. This behavior is caused by the technology.
3.3 Call waiting
Call waiting will be signaled as if connected to an ISDN network. The display text
and tone signaled is dependent on the configuration of the ISDN phone and will be
shown according to the ISDN phone features and settings (typical by an acoustic
tone and a display entry).
3.4 Call Hold / Enquiry
You can start an enquiry by the typical sequence as usual for the ISDN phone
(menu key or R key).

User Manual
Release r06 www.stollmann.de Page 12 of 18
3.5 Three party conference
You can start a three party conference by the typical sequence as usual for the
ISDN phone (menu driven).
3.6 Call forwarding
You can activate and deactivate call forwarding by the typical sequence as usual for
an analogue line by prefix codes. These codes are predefined by your service
provider.
Activation and deactivation is only possible by using the appropriate keys of the
ISDN phone (i.e. *21<phone number>). Activation and deactivation by using the
menu keys of an ISDN phone or an ISDN PABX is not possible.
3.7 Additional supplementary services
Additional services like call completion to busy subscriber, call transfer, etc. are not
available via the menu driven interface of the ISDN phone. These services are
defined by the services of the analogue lines and are controlled by keypad input
(DTMF tones). The display information of the ISDN phone is also not available.
Please refer to the services supported by your provider of the analogue lines.
