This is the info that I found...

Mbps Gateway
For digital connectivity, via both Digital Trunk Interface (DTI) and Primary
Rate Interface (PRI), North America uses 1.5 Mbps carriers programmed as Pulse Code Modulation Companding u-Law. Internationally, in places like Europe, 2.0 Mbps carriers programmed as Pulse Code Modulation
Companding A-Law are used. To interconnect these two types of switches,
gateways are used. A gateway switch performs conversion from A-Law to
u-Law, and u-Law to A-Law.

The North America 1.5/2.0 Mbps Gateway feature provides support for the
1.5/2.0 Mbps gateway functionality in the North American market, by
introducing software and hardware into North America that is already being deployed in International markets. This feature allows a Meridian 1 PBX to act as a gateway between a 1.5 Mbps Meridian 1 or Central Office switch programmed as u-Law, and a 2.0 Mbps Meridian 1 or Central Office switch programmed as A-Law. The Meridian 1 performs the conversion from A-Law to u-Law, and u-Law to A-Law.

Note 1: For a Meridian 1 to Meridian 1 connectivity, both switches must
be running Release 24 software (in LD 17, the RLS prompt must be set
to 24).

Note 2: This feature performs conversion from A-Law to u-Law, and
u-Law to A-Law. It does not provide interworking between the T-1 and
E-1 protocols. Only those features that are equipped on either side of the
gateway will be supported transparently across the gateway.

The 2.0 MBit (E-1) in North America capability allows an added bandwidth
capability to current Meridian 1 PBX customers, by introducing software and hardware into North America that is already being deployed in International markets. The Bearer channel (B-Channel) capability for PRI voice and data is increased from 23 to 30, and the A/B channels for DTI voice and data is increased from 24 to 30. For an nB+D configuration (nB+D is only supported in an MCDN environment, and not supported by QSIG), the B-Channel capability is 480.

Conversion scenarios

Scenario 1 - Gateway u-Law Meridian 1 connected to A-Law
Meridian/CO over an A-Law 1.5 Mbps connection
A North America (1.5 Mbps) Meridian 1 PBX, programmed as u-Law, is
connected to an International (2.0 Mbps) Meridian 1 PBX, programmed as
A-Law. The connection is over an A-Law 1.5 Mbps DTI/PRI link.
In this scenario, the conversion from A-Law to u-Law, and u-Law to A-Law,
is done at the Meridian 1 programmed as u-Law. It is this Meridian 1 PBX
that acts as the 1.5/2.0 Mbps gateway.

Scenario 2 - Gateway u-Law Meridian 1 connected to A-Law
Meridian/CO over an A-Law 2.0 Mbps connection
A North America (1.5 Mbps) Meridian 1 PBX, programmed as u-Law, is
connected to an International (2.0 Mbps) Meridian 1 PBX, programmed as
A-Law. The connection is over an A-Law 2.0 Mbps DTI/PRI link.
In this scenario, the conversion from A-Law to u-Law, and u-Law to A-Law,
is done at the Meridian 1 programmed as u-Law. It is this Meridian 1 PBX
that acts as the 1.5/2.0 Mbps gateway.

Scenario 3 - Gateway A-Law Meridian 1 connected to u-Law
Meridian/CO over an u-Law 1.5 Mbps connection
An International (2.0 Mbps) Meridian 1 PBX, programmed as A-Law, is
connected to a North America (1.5 Mbps) Meridian 1 PBX, programmed as
u-Law. The connection is over a u-Law 1.5 Mbps DTI/PRI link.
In this scenario, the conversion from A-Law to u-Law, and u-Law to A-Law,
is done at the Meridian 1 programmed as A-Law. It is this Meridian 1 PBX
that acts as the 1.5/2.0 Mbps gateway.

Scenario 4 - Gateway A-Law Meridian 1 connected to u-Law
Meridian/CO over an u-Law 2.0 Mbps connection
An International (2.0 Mbps) Meridian 1 PBX, programmed as A-Law, is
connected to a North America (1.5 Mbps) Meridian 1 PBX, programmed as
u-Law. The connection is over a u-Law 2.0 Mbps DTI/PRI link.
In this scenario, the conversion from A-Law to u-Law, and u-Law to A-Law,
is done at the Meridian 1 programmed as A-Law. It is this Meridian 1 PBX
that acts as the 1.5/2.0 Mbps gateway.

Can you find out which Release is required on an Option 11 to support card NTAK10AA? This card is installed in Ecuador but most of the sources I have found reference Europe.

Thanks.

Chas2002

Looking at Option 11C
2.0 Mb DTI/PRI Administration and Maintenance guide
Book one of two
Document Number: 553-3011-315

It looks like it depends upon the Feature Interactions you need..

CLID Enhancements feature introduced in Release 22 (this is the lowest release on my MERL) and All other entry's reference Release 24 and later...

Found this too....

For PRI2 connectivity - you'd need to following packages..
-- Integrated Services Digital Network (ISDN) package 145
-- 2.0 Mbps Primary Rate Interface (PRI2) package 154
-- Overlap Signaling (OVLP) package 184
-- International Primary Rate Access (IPRA) package 202
-- Multi-Purpose Serial Data Link (MSDL) package 222

Plus there is a ton of other info in there...

Do you want me to send you the PDF?

rlarin

I appreciate your prompt response. Please email the pdf to rick.larin@citigroup.com.

Cheers

Chas2002

R- The e-mail I sent exceeded your coorporate limits

I'll try again..

rlarin

Thanks, got it! Where can I get Doc# NTP 553-2911-200 (default abcd table with suggested values)?

Chas2002

R - I couldn't find that Document number in the Library...I sent you the closeset I could find.........

I did something similar in Suriname. However, we were interfacing the Dual Loop PRI cards to a Cisco router. If you are converting A-Law to Mu-Law, you need to make sure you have Package 167 (T1-E1 Gateway) in that Option 11C or you will have noise. We fought it for hours before I turned the package on and it cleared it. Everyone thought it was the Cisco and it wasn't.
