3 1.3 RADIO AND TV INTERFERENCE The NetLink-T1™ Model 2710 Series generates and uses radio frequency energy , and if not installed and used properly—that is, in strict accordance with the manufacturer's instructions—may cause interference to radio and television reception.
5 1.6 SERVICE INFORMA TION All warranty and non-warranty repairs must be returned freight prepaid and insured to Patton Electronics. All returns must have a Return Materials Authorization number on the outside of the shipping container .
7 2.3 SUPPORTED APPLICA TIONS The NetLink-T1™ CSU/DSU provides a T1 (DS1) network termi- nation between the service provider and customer premises equipment (CPE) such as a router . The Netlink-T1™ can also be used as a high- speed short haul modem for campus applications.
9 Switches SW1, SW2, and SW3 Use Switches SW1, SW2 and SW3 to set the DTE data rate. Each setting represents an nx56/nx64 setting. SW1 SW2 SW3 Speed Off Off Off Clear Channel (Unframed) On Off Off 1 1.
11 Switch SW6: Clock Mode Set Switch SW6 to determine the 2710’s transmitter timing. SW6 Clock Mode Off Network Clock . T ransmitter timing is derived from the received line signal. On Internal Clock . T ransmitter clock is derived from an internal oscillator .
13 4) When the unit is first turned on, the terminal screen may appear blank. Press the <Enter> key . If your serial connection is good, then the unit will immediately display a password prompt. The following message will appear in the middle of the screen: 5) T ype in the password and press <Enter>.
15 The Main Menu options are briefly described below . System Configuration options allow you to change various aspects of the NetLink-T1™’ s operation, e.g., framing, line coding, and aggregate bandwidth. System Diagnostics/Statistics options allow you to monitor the network performance, initiate V .
17 ESF: This stands for Extended Superframe Format, a line format developed by A T&T . A T&T T echnical Reference 54016 (TR 54016) defines the ESF , a format which is commonly used to allow monitoring of the network interface performance over the Facility Data Link (FDL).
19 Clocking : Network (default) Options: Network, Internal, External Network: This is the most commonly used setting when connect ing to a carrier ’s network. In this mode, the unit recovers the clock from the received signal and uses it to transmit data.
21 Remote In-band Loops : Enabled (default) Options: Enabled, Disabled In ESF , D4 and Unframed formats, the unit can respond to special repeating codes in the data stream that represent loopback com- mands. The command to loop up (go into loopback) is a repeating pat- tern of 00001s.
23 3.2.3 System Diagnostics The System Diagnostics/Statistics screen looks like this: NOTE: This screen is updated once per second. The System Diagnostics/Statistics options and functions are described below .
25 The NetLink-T1™ receiving a RL can be in one of the following states: RxPr The NetLink-T1™ is receiving a preparatory pattern. Sack The NetLink-T1™, upon receiving a preparatory pattern, sends an acknowledgement message. RL The NetLink-T1™ is in remote loopback mode.
28 Rx PRM The NetLink-T1™ transmits ANSI performance report messages once a second when the framing mode is ESF . When the ESF Data Link is set to ANSI T1.403, the unit recognizes PRMs with addresses of 38h or 3Ah. The address 3Ah indicates the PRM is coming from a Carrier , whereas the address 38h indicates the PRM is coming from a Customer .
29 3.2.4 Unit Options The Unit Options screen looks like this (factory default): Header Line 1 & Header Line 2 Headers 1 and 2 are provided for easy identification of your unit after installation. Y ou may want to give each unit a unique name via the header lines to help distinguish one unit from another .
32 4.3 POWER CONNECTION The NetLink-T1™ offers three ways to supply external power: AC power , DC power and interface power . 4.3.1 Using the AC Power Supply (120V AC or 100-240V AC) The NetLink-T1™ uses a 5VDC, 300mA 120V AC or universal input 100-240V AC, power supply .
34 LOS The Loss of Sync LED lights when the unit loses synchronization with the incoming sig- nal. This may happen when there is a fram- ing mismatch or a loss of signal. In unframed mode, the LOS LED monitors the status of the transmit clock. ALM The alarm LED indicates the presence of a Blue or Y ellow Alarm, or Out of Frame con- dition.
35 5.2 LOOP (V .54 & TELCO) DIAGNOSTICS The NetLink-T1™ offers three V .54 loop diagnostics and is com- patible with two T elco loop diagnostics. Use these diagnostics to test the CSU/DSU and any communication links. These tests can be acti- vated via the software control port (See Section 3.
37 5.3 BIT ERROR RA TE (V .52) DIAGNOSTICS The NetLink-T1™ offers three V .52 Bit Error Rate (BER) test pat- terns. These test patterns may be invoked along with the LAL and RDL tests to evaluate the unit(s) and the communication links.
39 APPENDIX B P A TTON NETLINK-T1™ MODEL 2710 CABLE RECOMMENDA TIONS The Patton NetLink T1™ Series has been performance tested by Patton technicians using twisted-pair cable with the following charac- teristics: W ire Gauge Capacitance Resistance 19 A WG 83nf/mi or 15.
