TAM1500-12  
12-Port T1 Access Multiplexer  
Net to Net Technologies strongly recommends the use of proper electrostatic discharge (ESD) precautions  
when handling this equipment.  
CAUTION  
INSTALLATION  
1. Unpack and inspect the TAM1500-12.  
If there is visible damage, do not attempt to connect the device; contact Customer Support at 1-  
877-638-2638 (001-603-427-0600 for international customers) or Support@NetToNet.com.  
2. Install the TAM1500-12 in an IP DSLAM chassis.  
There must be a Multiplexer Uplink Module installed in the IP DSLAM chassis in order for Access Modules to  
operate.  
NOTE  
All Access Multiplexer Modules for Net to Net Technologies' IP DSLAMs are hot swappable;  
installing or removing an Access Module while the chassis is powered up does not affect the  
operational status of other Access Modules within the chassis. The IPD12000 is a fourteen slot  
chassis; slots 1-12 are reserved for Access Modules (such as the TAM1500-12) and slots 13-14  
are reserved for Multiplexer Uplink Modules (such as the MUM200-2). Access Modules may be  
placed in any order in slots 1-12. The IPD4000 is a five slot chassis; slots 1-4 are reserved for  
Access Modules and slot 5 is reserved for a Multiplexer Uplink Module.  
a. Align the TAM1500-12 with the slot module guides of the chosen slot for installation (slot  
1-12 on the IPD12000 or slot 1-4 on the IPD4000).  
b. Slide the TAM1500-12 firmly into the chassis. DO NOT USE EXCESS FORCE.  
c. Secure the TAM1500-12 by tightening the fastening screws on the module faceplate.

Data Storage  
Configuration backup is inherent in the TAM1500-12. Upon initial power up of the IP DSLAM,  
the default parameters of the TAM1500-12 will remain in place unless changed through NMS.  
Once changed, new configurations will automatically be recorded in the Random Access  
Memory (RAM) of the TAM1500-12 and the Non-Volatile Random Access Memory (NVRAM) of  
the MUM. While data stored in TAM1500-12 RAM will be erased if the unit loses power, data  
stored within MUM NVRAM will remain intact (even if the unit loses power) unless deliberately  
cleared or reconfigured.  
TAM1500-12 CIRCUIT CONFIGURATION  
Circuit configurations common to all Access Module models are defined in the Management User  
Guide for IP and Mini DSLAMs. Circuit configurations specific to T1 technology are outlined below.  
Default settings for any of these may be altered via the Circuit Configuration window of Net to Net's  
Network Management System (NMS).  
Speed  
There are eight timeslot/bandwidth options for the T1 link; default is 1,536 kbps across all 24  
channels. Remote T1 modems determine line speed through their communication with the  
TAM1500-12.  
TAM1500-12 Timeslot & Bandwidth Options  
Timeslots  
1-3 1-6 1-9 1-12 1-15 1-18 1-21 1-24  
Bandwidth (kbps) 192 384 576 768 960 1,152 1,344 1,536  
 
210-0000025 rev04  
Although all 24 channels continually run at 1,536 kbps, the Timeslot configuration for each port determines  
how many of the channels will be receiving data for that port. Ports configured to operate as fractional T1  
lines require contiguous timeslots, as indicated in the table above.  
NOTE  
Frame Type  
Frame type is the T1 data encapsulation method. A frame consists of 193 bits (8-bit samples of  
each of the 24 T1 channels plus a synchronization bit) transmitted at a rate of 8,000 frames per  
second (1,544 kbps) across the T1 line.  
Super Frame  
Super Frame (SF) format assembles data into 12-frame transmission clusters.  
Extended Super Frame (Default)  
Extended Super Frame (ESF) format, used in Wide Area Networks (WANs), assembles data  
into 24-frame transmission clusters and integrates the following:  
!
!
Facilities Data Link (FDL) - communication support through in-service monitoring  
and diagnostics  
Cyclic Redundancy Check (CRC) - detects line errors and scrutinizes data integrity  
Line Code  
Line code is the T1 mode of transmission. The following line code options fall within the  
International Telecommunication Union - Telecommunication Standardization Sector (ITU-T)  
G.703 Standards for Transmission Facilities.  
Bipolar with 8 Zero Substitution (Default)  
Bipolar with 8 Zero Substitution (B8ZS) is used to accomodate the minimum ones density  
requirement in the North American public network. B8ZS line coding helps prevent loss  
of synchronization between the TAM1500-12 and remote T1 modems by using bipolar  
violations to guarantee there will always be pulses in the line.  
Alternate Mark Inversion  
The Alternate Mark Inversion (AMI) mode of transmission simply alternates positive and  
negative pulses. It is typical, with AMI, for a link to encounter long strings of zeros which  
can potentially cause loss of synchronization between remote units. Net to Net  
Technologies' products however, meet the North American minimum ones density  
requirement internally such that, even with AMI, loss of synchronization is prevented  
between the TAM1500-12 and remote T1 modems as it is with B8ZS line coding.  
Tx (Transmit) Buildout  
Shorter distances between the TAM1500-12 and remote modems require increasing line  
attenuation in order to prevent the T1 signal from becoming too strong for the repeaters,  
switches and other T1 transmission equiment that may be encountered along the line. Increased  
line attenuation translates into decreased transmit amplitude of the T1 signal.  
 
210-0000025 rev04  
0db (Default)  
Receivers on most newer T1 equipment (repeaters, switches, etc.) can automatically adjust  
for incoming amplitude, allowing them to run at zero attenuation regardless of distance.  
-7.5db, -15db or -22db  
Some older T1 equipment (repeaters, switches, etc.) cannot automatically adjust for  
incoming amplitude, in which case, it may be necessary to set attenuation manually  
(through NMS) from the choices above.  
Timing  
Local (Default)  
The transmit clock source will originate from an oscillator onboard the TAM1500-12.  
Loop  
The transmit clock source will originate from the remote T1 modem.
