== Description ==

The Protocol Tester K1103 has been developed for network supervision and network analysis of CCS#7, GSM, CDMA, ISDN D-channel, X.25 and V5.x protocols. A maximum of four different PCM links (T1/S2M) or V./X. links with up to eight signaling links (64 kbit/s, 56 kbit/s, 16 kbit/s) can be supervised simultaneously. More details [http://www2.tek.com/cmswpt/psdetails.lotr?ct=PS&lc=EN&ci=14411&cs=psu here] - unfortunately the service manual isn't public and I'm not allowed to upload it somewhere.

Indirect access to 4 of this machines can be given trough [mailto:holger@kernreaktor.org Holger].
